The Subterraneans

Underground settings are becoming increasingly relevant to global security and safety. Rising populations and urbanization are requiring military and civilian first responders to perform their duties below ground in human-made tunnels, underground urban spaces [e.g. mass transit, water infrastructure] and natural cave networks. Recognizing that innovative, enhanced technologies could accelerate development of critical lifesaving capabilities, DARPA today announced its newest challenge: the DARPA Subterranean Challenge.

The DARPA Subterranean or “SubT” Challenge aims to explore new approaches to rapidly map, navigate, and search underground environments. Teams from around the world will be invited to propose novel methods for tackling time-critical scenarios through unknown courses in mapping subsurface networks and unpredictable conditions, which are too hazardous for human first responders.

“One of the main limitations facing warfighters and emergency responders in subterranean environments is a lack of situational awareness; we often don’t know what lies beneath us,” said Timothy Chung, program manager in DARPA’s Tactical Technology Office (TTO). “The DARPA Subterranean Challenge aims to provide previously unimaginable situational awareness capabilities for operations underground.”

“We’ve reached a crucial point where advances in robotics, autonomy, and even biological systems could permit us to explore and exploit underground environments that are too dangerous for humans,” said TTO Director Fred Kennedy.“Instead of avoiding caves and tunnels, we can use surrogates to map and assess their suitability for use. Through the DARPA Subterranean Challenge, we are inviting the scientific and engineering communities—as well as the public—to use their creativity and resourcefulness to come up with new technologies and concepts to make the inaccessible accessible.

Like Wolves Like Drones: DARPA CODE

Most unmanned aerial systems (UAS) [i.e. drones] require constant control by a dedicated pilot and sensor operator as well as a large number of analysts, all via telemetry. These requirements severely limit the scalability and cost-effectiveness of UAS operations and pose operational challenges in dynamic, long-distance engagements with highly mobile targets in contested electromagnetic environments.  DARPA’s Collaborative Operations in Denied Environment (CODE) program aims to overcome these challenges by developing algorithms and software,,,with the goal of improving U.S. forces’ ability to conduct operations in denied or contested airspace.

CODE intends to focus in….the capability for groups of UAS to work together under a single human commander’s supervision….. CODE’s envisioned improvements to collaborative autonomy would help transform UAS operations from requiring multiple people to operate each UAS to having one person who is able to command and control six or more unmanned vehicles simultaneously. Commanders could mix and match different systems with specific capabilities that suit individual missions instead of depending on a single UAS that integrates all needed capabilities but whose loss would be potentially catastrophic.

“Just as wolves hunt in coordinated packs with minimal communication, multiple CODE-enabled unmanned aircraft would collaborate to find, track, identify and engage targets, all under the command of a single human mission supervisor,” said Jean-Charles Ledé, DARPA program manager.

Surveillance – Undress People Remotely

Officials from Guinness World Records today recognized DARPA’s Terahertz Electronics program for creating the fastest solid-state amplifier integrated circuit ever measured. The ten-stage common-source amplifier operates at a speed of one terahertz (1012 GHz), or one trillion cycles per second—150 billion cycles faster than the existing world record of 850 gigahertz set in 2012.…Developed by Northrop Grumman Corporation, the Terahertz Monolithic Integrated Circuit (TMIC) exhibits power gains several orders of magnitude beyond the current state of the art…  For years, researchers have been looking to exploit the tremendously high-frequency band beginning above 300 gigahertz where the wavelengths are less than one millimeter. The terahertz level has proven to be somewhat elusive though due to a lack of effective means to generate, detect, process and radiate the necessary high-frequency signals.  Current electronics using solid-state technologies have largely been unable to access the sub-millimeter band of the electromagnetic spectrum due to insufficient transistor performance…

According to  Dev Palmer, DARPA program manager. “This breakthrough could lead to revolutionary technologies such as high-resolution security imaging systems, improved collision-avoidance radar, communications networks with many times the capacity of current systems and spectrometers that could detect potentially dangerous chemicals and explosives with much greater sensitivity.”

DARPA has made a series of strategic investments in terahertz electronics through itsHiFIVE, SWIFT and TFAST programs. Each program built on the successes of the previous one, providing the foundational research necessary for frequencies to reach the terahertz threshold.

This technology can be used for Security and Communications (including military communications): Here from Wikipedia

Security:
Terahertz radiation can penetrate fabrics and plastics, so it can be used in surveillance, such as security screening, to uncover concealed weapons on a person, remotely. This is of particular interest because many materials of interest have unique spectral “fingerprints” in the terahertz range…. In January 2013, the NYPD announced plans to experiment with the newfound technology to detect concealed weapons, prompting Miami blogger and privacy activist Jonathan Corbett to file a lawsuit against the department in Manhattan federal court that same month, challenging such use: “For thousands of years, humans have used clothing to protect their modesty and have quite reasonably held the expectation of privacy for anything inside of their clothing, since no human is able to see through them.” He seeks a court order to prohibit using the technology without reasonable suspicion or probable cause.

 

 

Manipulation of Wireless Networks -Military

From the DARPA website and DARPA-BAA-14-44 WND Phases 2 and 3

The majority of work to develop and mature military wireless networks to date has focused on efficiency and stability in benign conditions…As the use of wireless systems expands, the likelihood of network compromise (whether maliciously or by unwitting misconfiguration) will increase. Beyond the conventional node-by-node security in use today, a set of network-based checks are needed to ensure that misinformation inserted into the control protocols does not disable the network functionality.

The Wireless Network Defense (WND) program is developing and demonstrating new technology to protect the control protocols of wireless networks from the effects of advanced attacks or other forms of compromise. The program focuses on the protocols at the network and medium access control (MAC) layers of the network stack with the goal of protecting those protocols that coordinate among the distributed devices’ management of resources such as spectrum, time, and power, and delivery of information.

The development of this technology will both improve the robustness of the class of wireless networks that are being procured and fielded in the near future, and also provide a reliable foundation on which to build the next generation of wireless systems. These new defenses will minimize the impact of attacks on network control and will force attacks to be observable and attributable in order to be effective.

Ideally…[one] should anticipate both passive listeners and active attackers; colluding attackers; dynamic attacks; and informed adversaries…[One]should assume that passive listeners and  active attackers will be able to collude. That is, the threat model is a real-world adversary.  Systems should be designed to mitigate attacks under all combinations of attackers and attacks…. [One]should further design mitigations and enhancements such that these mitigations and enhancements cannot themselves be leveraged by a knowledgeable adversary to attack the network.

A New GPS for the Military

Teaming up with Northrop Grumman as its primary contractor, DARPA is working today to integrate micro-electro-mechanical systems, called MEMS, and atomic inertial guidance technologies, forming a new “single inertial measurement unit” in a project designated the “Chip-Scale Combinatorial Atomic Navigator” — C-SCAN.

Translated into plain English, what C-SCAN aims to accomplish is to create a chip that performs the functions today served by orbiting GPS satellites. The chip would constantly “know” where it is in space-time, and would have this knowledge without having to ping a satellite (and maintain line-of-sight communication with a satellite) to do it… Elimination of the need to rely on satellites to determine one’s location would similarly enable the use of “GPS-like” technology for getting directions within buildings and underground — for example, in subway systems…

One of the primary vulnerabilities in today’s hi-tech, ultra-accurate weapons systems, you see, is their dependence upon GPS signals to guide them to their destinations. American “smart bombs” and guided missiles all depend greatly on GPS to know where they are, and to get where they’re going. American dominance in drone technology, similarly, depends on GPS.  Problem is, while we know this is a problem, the “bad guys” know it, too — and can sometimes hack GPS signals so as to confuse, and even hijack, American weapons systems. Case in point: in 2011, Iran boasted that it had commandeered and captured a Lockheed Martin RQ-170 Sentinel — one of our most advanced “stealth” surveillance drones — in flight over Iranian territory. The Iranians didn’t have to shoot the drone down, either. Instead, they forced it to land in Iran, and captured it intact. According to Iranian engineers, this was accomplished by first jamming communications with the Sentinel’s remote controllers, then “spoofing” GPS signals, tricking the drone into landing at what it thought was its home base in Afghanistan — but what was actually an Iranian airfield.

Drones equipped with a future C-SCAN technology would be less likely to fall victim to such a trap. While their communications might be cut off, forcing them to default to autopilot and return to base, they’d at least return to the right base, because an internal chip would tell them how to get there.

Current weapons systems often include internal gyroscopes, granted, that perform some of the functions that C-SCAN aims to perfect. But as DARPA observes, present-day gyroscopes are “bulky” equipment, “expensive,” and don’t perform with the kind of accuracy that DARPA wants to see.  The objective, therefore, is to explore cutting edge technologies to put gyroscope-like functionality on a chip, resulting in “small size, low power consumption, high resolution of motion detection and a fast start up time” — all loaded onto one small microchip….

Microchip-based guidance could be the solution the military is seeking to an oft-discussed problem with the nation’s newest generation of Mach 7 railguns, whose great range, speed, power — and cheapness — make them an attractive weapons system… if we can only figure a way to guide their projectiles accurately

Human – Machine Interfaces

From the DARPA website

The mission of the Biological Technologies Office (BTO) is to foster, demonstrate, and transition breakthrough fundamental research, discoveries, and applications that integrate biology, engineering, and computer science for national security. BTO seeks to establish and invest in new communities of scientific interest at the intersection of traditional and emerging disciplines. Its investment portfolio goes far beyond life sciences applications in medicine to include areas of research such as human-machine interfaces, microbes as production platforms, and deep exploration of the impact of evolving ecologies and environments on U.S. readiness and capabilities. BTO’s programs operate across a wide range of scales, from individual cells to complex biological systems including mammalian and non-mammalian organisms and the macro- and micro-environments in which they operate.

BTO Focus Areas

Restore and Maintain Warfighter Abilities Military readiness depends on the health and wellbeing of military service members. A critical part of BTO’s mission is to cultivate new discoveries that help maintain peak warfighter abilities and restore those abilities as quickly and fully as possible when they are degraded or lost. This focus area is grounded in the development of new techniques and therapeutic strategies for addressing current and emerging threats, but extends beyond medical applications to include exploration of complex biological issues that can impact an individual’s ability to operate and interact in the biological and physical world. The research portfolio includes neuroscience to drive a deeper understanding of the human brain, how it interfaces with the body and the external world, and how it directs and coordinates behavior, including decision-making in demanding environs. BTO will extend work involving human participants and apply insights from physiology, biochemistry, psychology, sociology, and related sciences to such emerging-science domains as bioengineering, bioinformatics, and microbiomics.

Harness Biological Systems The highly evolved functional and synthetic capabilities of biological systems can be harnessed to develop new products and systems in support of national security with advantages over what even the most advanced conventional chemistry and manufacturing technologies can achieve. This space and its opportunities are just becoming tangible due to the rapid, simultaneous development of genome-scale engineering tools, enormous genomic datasets, new analytical capabilities, and the convergence of several engineering and scientific disciplines with biology. BTO seeks to establish a fundamental understanding of natural processes and the underlying design rules that govern the behavior of biological systems, and apply that knowledge to forward-engineer new systems and products with novel functionality. To support this work, BTO develops techniques at the intersection of automation, computer science, and biology to explore biological data at massive scales.

Apply Biological Complexity at Scale Biological systems operate over an enormous range of spatial, physical, and temporal scales. Some organisms thrive as individual cells, while many others, including humans, are colonized by communities of foreign cells that greatly outnumber their own and have potentially significant but still largely mysterious impacts on metabolism, psychological state, performance, and health. Disease vectors migrate around the globe slowly and stealthily at times, and at other times in devastating waves of breathtaking speed—poorly understood dynamics that can threaten national security. And because they are so difficult to parse from larger biological and ecological phenomena, population-level effects of relevance to agriculture and food security remain largely unplumbed. BTO is looking into pursuing new insights derived from biological complexity and living-system dynamics with the goal of developing applications to enhance global-scale stability and human wellbeing.
