TDOA-Enhanced Geolocation For the Team Portable Collection System

An innovative system for geolocation of emitters in the field is proposed. The system integrates short baseline calibration methods and the effects of platform motion with recent emitter location advances by Signatron Technology Corporation that combines TDOA, DF, and signal strength in directly optimized location estimate. The system requires significantly less data to be transmitted than conventional TDOA systems. The system uses signal decomposition to isolate only those signal characteristics necessary for locating, thus minimizing the required data communication bandwidth. The system is suitable for implementation as modular plug-in modules and is scaleable in the sense that modules can be added to increase the capacity of the system, making it ideally suited for integration with the Team Portable Collection System. In Phase I, the system performance will be established using analysis and computer simulations. Sensor self-positioning, synchronization, and calibration procedures will be established. A prototype demonstration is planned for Phase II.
