The goal is to develop low-cost, rapidly updatable intelligence, surveillance and reconnaissance (ISR) sensors in less than a year, a marked improvement to the current three-to-eight year development process.

2013/05/22 Warrior Web Prototype Takes Its First Steps

DARPA Public Affairs Office — Wed, 22 May 2013 17:35:00 GMT

A Soldier carries a 61-pound load while walking in a prototype DARPA Warrior Web system during an independent evaluation by the U.S. Army. Warrior Web seeks to create a soft, lightweight under-suit that would help reduce injuries and fatigue common for Soldiers, who often carry 100-pound loads for extended periods over rough terrain. DARPA envisions Warrior Web augmenting the work of Soldiers’ own muscles to significantly boost endurance, carrying capacity and overall warfighter effectiveness–all while using no more than 100W of power.

2013/05/15 DARPA Seeks Technology to Radically Improve Dismounted Squad Situational Awareness, Communication Effectiveness

DARPA Public Affairs Office — Wed, 15 May 2013 13:28:19 GMT

Success on the battlefield requires warfighters to know as much as possible about themselves, their surrounding environment and the potential threats around them. Dismounted infantry squads in particular risk surprise and loss of tactical advantage over opponents when information is lacking. While squads use many different technologies to gather and share information, the current piecemeal approach doesn’t provide the integrated, real-time situational awareness needed for individual warfighters and squad leaders to anticipate situations and effectively maneuver to positions of advantage. Providing this capability would provide dismounted squads with overwhelming tactical superiority over potential adversaries similar to what warfighters enjoy at the aircraft, ship and vehicle levels.

2013/05/14 Choose Your Own Sociocultural Training Adventure

DARPA Public Affairs Office — Tue, 14 May 2013 16:33:10 GMT

The wars in Afghanistan and Iraq demonstrate the strategic significance of tactical actions by junior and noncommissioned officers who interact with local populations. This kind of interaction benefits from extensive cultural training, but opportunities for such training are limited by the compression of the Department of Defense’s force-generation cycles. Virtual training simulations provide a partial solution by offering warfighters on-demand, computer-based training, but creating such tools currently requires substantial investments of time, money and skilled personnel.

2013/05/08 Rapid Threat Assessment Could Mitigate Danger from Chemical and Biological Warfare

DARPA Public Affairs Office — Wed, 08 May 2013 13:20:01 GMT

For more than fifty years, researchers have been studying exactly how aspirin affects the human body. Despite thousands of publications on the topic, our understanding is still incomplete.

2013/05/02 Quantum-assisted Nano-imaging of Living Organism Is a First

DARPA Public Affairs Office — Thu, 02 May 2013 14:25:38 GMT

In science, many of the most interesting events occur at a scale far smaller than the unaided human eye can see. Medical researchers might realize a range of breakthroughs if they could look deep inside living biological cells, but existing methods for imaging either lack the desired sensitivity and resolution or require conditions that lead to cell death, such as cryogenic temperatures. Recently, however, a team of Harvard University-led researchers working on DARPA’s Quantum-Assisted Sensing and Readout (QuASAR) program demonstrated imaging of magnetic structures inside of living cells. Using equipment operated at room temperature and pressure, the team was able to display detail down to 400 nanometers, which is roughly the size of two measles viruses.

2013/04/30 New Method Joins Gallium Nitride and Diamond for Better Thermal Management

DARPA Public Affairs Office — Tue, 30 Apr 2013 20:06:44 GMT

Many military radio frequency (RF) systems, like radar and communication systems, use a class of power amplifiers (PAs) called monolithic microwave integrated circuits (MIMIC). MMIC PAs using gallium nitride (GaN) transistors hold great promise for enhanced RF performance, but operational characteristics are strongly affected by thermal resistance. Much of this resistance comes at the thermal junction where the substrate material of the circuit connects to the GaN transistor. If the junction and substrate have poor thermal properties, temperature will rise and performance will decrease.

2013/04/30 DARPA Seeks Clean-Slate Ideas For Mobile Ad Hoc Networks (MANETs)

DARPA Public Affairs Office — Tue, 30 Apr 2013 14:22:19 GMT

Troops operating in forward locations without telecommunication infrastructure often rely on a mobile ad hoc network (MANET) to communicate and share data. The communication devices troops use on foot or in vehicles double as nodes on the mobile network. A constraint with current MANETs is they can only scale to around 50 nodes before network services become ineffective. For the past 20 years, researchers have unsuccessfully used Internet-based concepts in attempts to significantly scale MANETs.

2013/04/16 Smaller Pixels, Smaller Thermal Cameras for Warfighters

DARPA Public Affairs Office — Thu, 25 Apr 2013 18:34:52 GMT

The military uses long-wave infrared (LWIR) cameras as thermal imagers to detect humans at night. These cameras are usually mounted on vehicles as they are too large to be carried by a single warfighter and are too expensive for individual deployment. However, DARPA researchers recently demonstrated a new five-micron pixel LWIR camera that could make this class of camera smaller and less expensive.

2013/04/10 Extreme Miniaturization: Seven Devices, One Chip to Navigate without GPS

DARPA Public Affairs Office — Thu, 25 Apr 2013 18:34:37 GMT

The U.S. Military relies on the space-based Global Positioning System (GPS) to aid air, land and sea navigation. Like the GPS units in many automobiles today, a simple receiver and some processing power is all that is needed for accurate navigation. But, what if the GPS satellites suddenly became unavailable due to malfunction, enemy action or simple interference, such as driving into a tunnel? Unavailability of GPS would be inconvenient for drivers on the road, but could be disastrous for military missions. DARPA is working to protect against such a scenario, and an emerging solution is much smaller than the navigation instruments in today’s defense systems.
