Bistatic Radar Receiver/Processor

This multi-phase program will develop an accurate automated passive, single-airborne-platform, non-cooperative emitter geolocation capability which utilizes radar transmissions and leverages knowledge-aided techniques. This capability will include the ability to utilize varied information sources, when available, to determine emitter location coordinates within timelines relevant to real-time mission operation. These information sources include, but are not limited to, operator inputs; a-priori emitter surveys; emitter scan parameters and waveform characteristics; and Digital Terrain Elevation Data (DTED) and Land Use and Land Cover (LULC) databases. We will leverage the results and hardware of our recently completed program which built an airborne prototype system capable of synching to a non-cooperative emitter and processing the bistatic radar returns to track illuminated airborne and surface moving targets passively. This system will be the starting point for this effort, providing the synchronization and clutter map data needed to perform automatic emitter geolocation. In addition previous bistatic geolocation IR&D research will be leveraged. The integrated system would be capable of collecting clutter map data that could be used to, within a period of few minutes or less, locate a circularly-scanning surveillance radar to within 1 km or better by correlating with terrain data.
