Real-time simulations of underwater acoustic targets, underwater backgrounds, and the marine environment must be carried out during the semi-physical simulation of the self-guided system of torpedoes. In this paper, based on the semi-physical simulation of the self-guided system of torpedo searching, the key technologies of real-time generation and real-time control of target background are discussed. The technical solution of real-time simulation of underwater target background using parallel computation of multiple DSP is proposed. The underwater acoustic signal generation and control of real-time technology bottlenecks, given the system configuration and control programs. Through the simulation test, the system meets the engineering requirements of semi-physical simulation of torpedo-guided system.
