The advantage of using correlation methods of signal processing is the maximum effectiveness of the obtained estimates of time
de-lays in the presence of additive noise. In the case of several sources of signals simultaneously present in the sounding region, the traditional correlation method faces the problem of ambiguous interpretation of the results of measuring time delays. The advantages of methods and methods for suppressing «anticorrelation» signals in two-dimensional correlation processing consisting of the maxi-mum efficiency of the obtained estimates of time delays in the presence of additive noise are analyzed. The main types and charac-teristics of «anticorrelation» signals with a description of the principles of adaptive formation of the interference model are presented. It has been revealed that the effectiveness of protection against powerful interference depends on the accuracy of the estimation of the interference amplitude in the adaptive receiver, while the absence of a priori information regarding the type of signal and inter-ference and, accordingly, their characteristics, does not effectively suppress a large class of the above-described interference.
