Abstract The imitating model of functioning of bistatic sonar system placed on moving carriers is de-scribed herein. As parameters of efficiency in offered model signal-to-clutter ratios depending on a relative bearing of the purpose and depths of the carrier sonar and entity of search, the area of a zone of detection on the set depth of the purpose are used at set instant probability of correct de-tection and probability of a false alarm for a cycle of a location, a field of instant probabilities of correct detection and root mean square errors of a position fixing of underwater entities depending on a relative bearing and depth of the purpose, and also the cumulative probability of detection of the purpose maneuvering with a set speed and a rate and on set depth for the set moment of time. Features of model are the account of kinematic characteristics of search of-speed and depth of the carrier and entity, associations of a reflectivity from course and bistatic angles of the purpose, characteristics of an acoustic propagation in the sea in radiation approaching and technical parameters of sonars. Also characteristics of the noises cause by noises of a marine environment, by noises of the carrier, a hydrodynamic component of noises, irradiations of local sources, monostatic and bistatic reverberation noises are considered. The estimation of effect of organization of the observation defined by modes of functioning in each sonar-monostatic, bistatic or combined, when one or both simultaneously function in monostatic and bistatic modes. Simulation modeling is effected on the time steps linked to cycles of a location. Program realization of a technique is developed for a personal computer in language C ++ in Builder-6 environment on the basis of usage of technology of object-oriented designing. Examples of calculations of probabilities of detection and errors of a position fixing of entities bistatic sonar system are presented by the system consisting of two interfacing sonars of type of export product MGK-335EМ-03 in sample for shallow-water area conditions of observation and a negative refraction of velocity of a sound at movement of the carrier and the purpose on counter rates.
