GAUSS: The GTRI airborne unmanned sensor system

Georgia Tech Research Institute is developing under IRAD funds a small unmanned aircraft system (SUAS) testbed for advanced RF sensor data collection and post-collection algorithm evaluation and fusion of multi-INT ISR sensor suites. The GAUSS testbed is reconfigurable to test STAP algorithms, multistatic and MIMO operation among multiple flying SUAS platforms, interferometric applications of crossplatform coherence, waveform diversity modulations other than traditional radar modulations, software agile radar, and sensor fusion. The initial configuration of GAUSS consists of an 8-phase-center (8 channels) X-band GMTI radar, a SIGINT DF system, and a gimbaled stabilized camera ball. The eight phase centers can be driven by independent digital 1 Gsps arbitrary waveform generators for true waveform diversity programming. This presentation will present the capabilities of GAUSS and future plans for collaborative missions in the ISR community.
