Tracking Algorithms for Multi-Static Passive Radar Systems

ABSTRACT: Air defense systems using Passive coherent location (PCL) radars are a concern for the US Air Force because of the PCL receivers"reduced vulnerability to electronic detection and precision weapons, and because of their potential for enhanced detection of low-observable US aircraft. The Electronic Combat Benchmark Tool (ECBT) is a detailed simulation of an integrated air defense system used by the air force for planning missions and developing electronic attack techniques. However, this tool is currently limited to monostatic radars. The proposed Phase I program will produce a comprehensive plan to upgrade ECBT to handle air defense systems that use PCL radars. The proposed work includes an assessment of the tool, and the development of algorithms and models for PCL radar simulation, including multistatic radar modeling, single-receiver tracking with multiple transmitters, and multiple-receiver integrated tracking. The proposed work draws on TSC"s extensive experience in bistatic radar simulation, design and testing. BENEFIT: The proposed program will outline the models and algorithms that are required to provide a complete tracking simulation for a ground-based passive coherent location (PCL) in the Electronic Combat Benchmark tool. These results will lay the groundwork for the implementation of this capability in a Phase II program.
