TSC has developed a Threat Emitter Geolocation System (TEGS) to provide low-resolution geolocation information on detected ground-based emitters. It employs a highly sensitive (< -100 dBm) intercept receiver, originally developed by TSC to detect LPI radars, coupled with broadband/broad-beam dual-polarized antennas and powerful geolocation estimation and tracking algorithms to determine and refine the locations of detected emitters, while minimizing the effects of multipath, atmospheric attenuation, and other interfering signals. Unlike typical, high-resolution geolocation systems and techniques, TEGS relies on non-time correlated information gathered from several unmanned air systems (UAS), or other platforms of opportunity.
The hardware components of the TEGS are small, lightweight, and power-efficient, to accommodate UAS size, weight, and power (SWaP) constraints. The measured information is expected to be partially processed onboard the airborne platform, but must be fused with all airborne platform information, most likely in a processor onboard the mobility service aircraft or jammer, for the final emitter geolocations.
