Influence of Target Motion Factors Error on Calculating Ultimate Range of Wire Guided Torpedo

This paper establishes a simulation model for calculating the ultimate range of wire guided torpedo to attack a moving warship with rectilinear uniform velocity based on the analysis of calculation method of ultimate range of wire guided torpedo and influence factors. The model employs the method of target bearing modification to launch torpedo, uses the "keeping distance for wire and wake guide" method on wire guided distance and the wake homing mode on homing pursuit distance. The ultimate ranges of torpedo are calculated with different errors of target motion factors according to the surface ship′s velocity and board angle values as well as their error scope obtained from command and control system. Furthermore, the calculation result is evaluated to improve acquisition probability of wire guided torpedo.
