Abstract
The stochastic task of mutual detecting, estimating the number and angle position of slow-moving targets is formulated. The angular resolution algorithm for targets is built on the principle of statistical hypotheses testing. The concept of resolution, in contrast to the Rayleigh energy criterion, involves setting a numerical value for the probability of correct resolution (i.e., the probability of correctly indicating the number of targets in the zone of responsibility of the observation system). A priori information about the characteristics of signals and interference, when targets are moving, as well as their probabilistic properties, allows to build a signal processing procedure that provides a high resolution exceeds the energy limit criterion of Rayleigh. It is shown, that resolution win becomes higher when the signal-to-noise ratio is growing up. The digital signal processing procedure is performed in real time only under the assumption of linear unidirectional movement of targets relative to the antenna system of the radar. Analytical relations for the procedure of jointly detecting the targets and measuring the angle of arrival of their signals based on analysis of statistical hypotheses are obtained. The main performance characteristics of the radar system are calculated. Recommendations on the implementation of digital signal processing algorithms for real-time operation are given.
