Raytheon Company has successfully developed and demonstrated a revolutionary new signals exploitation system that weighs 10 times less than conventional technology. Developed under DARPA's Smart Module program, Combat Cueing is a human-portable system that provides radio frequency (RF) situational awareness to small military units, allowing the warfighter to detect and locate in real time low-probability-of-intercept (LPI) transmitters operating between 30 and 88 MHz. Raytheon conducted field demonstrations of Combat Cueing at Ft. A.P Hill, VA. System modules, mounted on HMMWV military vehicles, successfully detected and located threat radios with 250 meter accuracy. The system employed a novel baud-phase time-difference-of-arrival (TDOA) algorithm, which calculated emitter locations by measuring demodulated signal symbol (baud) arrival times at each of the modules. By simultaneously reducing the space, weight, power and cost of conventional systems, these all-weather modules are operational across a broad spectrum of platforms, including tactical ground vehicles, robots, unmanned aerial vehicles, helicopter and ships, or may be left unattended on buildings, towers or the battlefield.
