Interference Rejection and Detection Performance of the Smallest of Circuit

Abstract

Radar systems encounter severe interference when other nearby systems operate on the same frequency. Usually, this type of interference is eliminated with a binary integrator or M-out-of-N detector. The loss of amplitude information is a disadvantage incurred with this type of detector, also the detection performance is worse than that of a detector that integrates the signal prior to thresholding. This report describes the means of eliminating asynchronous interference by amplitude comparison of consecutive radar sweeps; the smaller of the two is retained. Interference is eliminated, amplitude information is retained, and the detection performance is shown to be only 0.7 dB worse than that of a moving window integrator. (rrh)
