Radio-electronic conflict between interference suppression communication systems (CS) and modern suppression systems (SS) is considered with a view to game-theory model. On basis of ergative (man-machine) approach it-s shown that for SS interferences in the part of the band according to CS with broadband signals (BBS) and return traced interference according to CS with pseudorandom operating frequency tuning (POFT) are dominated for SS. Frequency tuning rate is a competitive point in CS and SS and it has the decisive influence on conflict result. It-s shown that the important role plays receiver noises of the CS transmitter. Independence on any SS parametric effects can be achieved at the definite level, the level of SS noise signal doesn-t influence on the conflict result. It-s shown also that optimal solutions for CS lies in the field of composite strategy: it-s a communication system with pseudorandom hopping of broadband signal (PHBS). Implemented researches are supported by specific test results, including in radio-electronic conflicts of communication and control systems, developed for the benefit of Department of Defense and defense enforcement agencies. In realized short waves communication system based on PHBS technique one could bring to round-the-clock communication reliability up to 0,98.
