The use of non-Gaussian character of echo signal distribution in moving target detection systems

Abstract

In this paper we developed algorithm for detection non-Gaussianity of the signal and noise mixture. Noise at a radar receiver input has Gaussian distribution, but mixture of noise and useful signal tends to be non-Gaussian. Thus, presence of useful echo signal in the mixture can be detected with use of the proposed algorithm. Further processing in moving target detection system allows distinguishing between echo signals from stationary targets and moving ones.
