Abstract
A process for cancelling the effects of noise jamming in a radar system having a dual-polarization monopulse antenna, a computer processor, and target detection algorithms, wherein the noise jamming produced by a hostile electronic countermeasure on a target is cancelled so as to detect the target in the optimum detection channel. The process consists of the steps of receiving signals from multiple monopulse polarization aperture combinations of the radar antenna, sampling the signals from the radar antenna, digitizing the sampled signals, calculating combination values based upon the samples of the digitized signals, computing several potential target detection channel signals based upon the combination values and samples of the digitized signals, applying the detection channel signals to the computer processor and selecting the optimum detection channel signal for detection of the target using the computer processing whereby the signal is then applied to target detection algorithm of the radar processor.
