The article is devoted to the development of algorithm of radio of signals in the spectral range of multiple monopulse direction finders. As observed data is considered the totality synchronously measured in each observation of complex amplitudes of voltage in the channels of radio receiver. Detection algorithm assumes the formation of estimation the mean of the modulus of spatial correlation coefficient stresses in pairs of adjacent channels the radio receiver. The decisive statistics algorithm is formed of diagonal and addiionally matrix elements of mutual energies stresses, "accumulated" a set of measurements. Decision rule algorithm is adaptive to unknown adaptive noise intensity receiving channels, dynamical characteristics of the antenna system and the transfer factor radio channel. According to the results of simulation modeling of the detection algorithm is proposed or the approximation of the distribution decisive statistics beta distribution in accordance with the Chi-square. Within this approximation the analytics expressions for the probability of false alarm is received. Article contains 10 bibliographic sources of the information.
