Demonstration of Advanced Detection Techniques Against Low Probability of Intercept Avionics Waveforms

"Condor will develop and demonstrate a system that detects, finds direction of arrival of, and correctly identifies weak signals from air vehicle radar altimeters, both pulsed and FMCW types. This Phase II proposal is based on work performed during thePhase I and Condor's previous research and on-going IRAD work. Condor has high confidence in our system modeling predictions. We believe that we will meet the performance goals of altimeter processing sensitivity, high accuracy azimuth angle of arrivaland resolution, identification accuracy, and signal discrimination. Signals will be collected with high-speed data acquisition hardware, processed using new algorithms, and displayed using existing analysis software called SPT.The system includes an interferometer array antenna, wideband receiver, custom-built wideband digitizers, high-speed data acquisition, and a high performance workstation. Condor will demonstrate system performance in both laboratory and field tests.Our approach does not require specialized high-speed signal processors or new signal intelligence databases.This proposal is a significant step towards a commercially available, low-cost receiver and VME card processor that would serve as an adjunct to conventional ESM/ radar. Condor's experience in development and production of ESM systems uniquely qualifiesus to carry out this program."
