Abstract
A digital missile warning system comprising a distributed pulse doppler radar having a plurality of antennas, each being coupled to a transmit/receive (T/R) module located adjacent to the antenna, and parallel signal processing channels including an A/D converter, FFT processor and a range/velocity track file processor in each channel for each antenna resulting in enhanced detection range, reduced False Alarm Rate (FAR), faster response time, reduced size, weight and installation requirements, improved reliability and reduced acquisition and life cycle costs. An optional optical missile warning system can provide azimuth and elevation data to the track file processors which enables a three (3) dimensional track of a missile, with azimuth and elevation angles provided by the optical system and range, velocity and acceleration data provided by the pulse doppler radar. The combination of Pulse Doppler Radar MWS and the Optical MWS produces close to a zero False Alarm Rate (FAR). Further, means to extract a threat IR missiles'"'"' roll rate and its seeker spin rate and phase angle are provided.
