Abstract:Under the background of submarine launches wire- guided torpedo to attack surface warship through target motionanalysis after passive sonar system of submarine tracking target, mathematical model of torpedo guidance method, sonar target reso-lution, and target motion analysis is established. Influence of submarine tactical maneuver on attack effectiveness of wire-guide tor-pedo attacking remote water surface after being launched is studied by simulation. According to Monte Carlo simulation method oftorpedo operational effectiveness, for the attack efficiency of torpedo weapon system, the requirement of submarine tactical maneu-ver which meets wire-guide torpedo attack effectiveness indexes under certain target motion element error after launch of torpedo ispresented, and the design scheme of weapon system which meets the requirement is given.
