This article presents the results of research masking properties of multiple simulation-noise interference. The study was conducted by a comparative analysis of the performance of the detector signals on the background of multiple simulation-noise and noise interference. Expressions are obtained for the probabilities of correct detection and false alarm in the case of detection of signals in the radar background multiple simulation-noise interference. Described dependence of the probability of correct detection of reflected signals from radar ratio interference/signal for various values of the probability of false alarm, the intensity of the flow of simulated signals, the proportion of interference power, used to simulate the signals, base signal that detects radar. It is shown that multiple simulation-noise interference in addition to misinform properties has some good masking capabilities and can be recommended as a universal obstacle to jamming radar. Moreover, multiple simulation-noise interference can be successfully applied not only for violation of the stages of secondary processing of radar data, but also at the stage of initial detection of radio radar.
