Research on the optimization of the fire control parameters for multi-speed torpedo

According to the technical conditions of guidance and the fire control for torpedo, based on a proper coordinate system, a kinematic model of the search trajectory of torpedo was established, and the optimal configurations of high speed and low speed were analyzed for the multi-speed torpedo. Aiming at the problem of large undershooting quantity in the case of the big bow bearing from target, an estimation method for speed and the course of target was proposed in this paper, and a computation method of advance angle for torpedo firing was given. By employing Monte Carlo method, detection probabilities were simulated to attack targets with the different speed or course using different fire-control parameters. The simulation results show that, the proposed method can improve the target detection probability effectively for torpedo.
