DARPA hybrid analog, digital, photonic and electronic processor technologies for real-time signal intelligence

U.S. military researchers are asking for industry’s help in developing a combination hybrid analog, digital, photonic, and electronic processor to help analyze RF and optical signals for situational awareness. The project seeks to enable U.S. and allied warfighters to understand in near-real-time all the waveform details, source type and class, …

DARPA developing software-reconfigurable Passive and Active (LIDAR) imaging sensors from ultraviolet (UV) through very long-wave infrared (VLWIR)

Digital cameras use a focal plane array (FPA) to convert light energy into electrical energy that can be processed and stored. The FPA is a two-dimensional (2-D) array of photodetectors (or pixels) fabricated on an electro-optical material. Modern digital cameras contain FPAs that have pixel counts on the order of …

US DOD developing space surveillance, Rendezvous and Proximity Operations capability in geosynchronous orbit for space deterrence

The most important element of space is geosynchronous orbit, a circular orbit 22,300 miles above the planet where satellites appear to be stationary above the surface of the earth. British science fiction writer, futurist and inventor Arthur C. Clark mathematically determined the orbit in 1947, the general said.   The …

DARPA investing in breakthrough camera technologies like 4D camera, seeing around corners and digitally mapping the room for urban and unconventional warfare

Urban Warfare Operations are complicated by a three-dimensional environment, limited fields of view and fire because of buildings, enhanced concealment and cover for defenders, below-ground infrastructure, and the ease of placement of booby traps and snipers. DARPA  is  investing in many novel camera technologies . In the event of urban …

New polarizer technologies can aid in detecting military targets from high altitude air and space platforms

Many types of sensors have been proposed for detection of small targets such as tanks and trucks including passive infrared imaging sensors and active Radars. Passive sensing systems, for many types of targets, especially airborne ones, use target motion as a cue for the target detection. However, for stationary small …
