The PinPoint System Definition Study
By:
Published on 2001 by
The purpose of the PinPoint program is to integrate adaptive beamforming techniques for co-channel interference cancellation with Time Difference Arrival - Differential Doppler (TDOA-DD) processing for rapid and precise geolocation of low-power tactical emitters in a dense co-channel environment. The end goal of the PinPoint program is to demonstrate the battlefield imaging technology required to provide the commander with a highly sensitive, robust, precise and real-time geographical awareness of the tactical emitter scenario. The PinPoint program is structured as a multi-phase effort beginning with the Phase 0 study reported on herein. The PinPoint Demonstration System will be developed in Phase I, currently under contract. In Phase II the system will be integrated with a suitable multi-antenna collection system such as, but not strictly limited to, LBSS or the Army Testbed Unit. Flight testing is planned for Phase III. The Phase 0 program was a feasibility study to identify and address the critical technology risk areas associated with integrating beamforming with precision geolocation, through a combination of analysis, algorithm development, simulation, and architecture trades.
