Abstract
Results of the synthesis of an algorithm for optimal signal detection, which consists in alternating sign conversion of received signals in time and compensation of the interference signal during accumulation in the filter, are presented. The physical basis of the algorithm synthesis is the differences between the time-frequency characteristics of the signals reflected from a moving target and the earth's surface, manifested in the time shift of the maximums of the useful and interference signals with equal Doppler frequency shifts. The processing algorithm compares the modulus of the weight integral with the threshold. A block diagram of an optimal detector is developed. The dependence of the weight vector of optimal processing normalized by amplitude on time is considered. The potential performance of moving target detection is assessed. It is shown that when detecting low-speed targets, there are optimal scanning speeds at which the probability of correct detection is maximum.
