Abstract

In this paper, a simulation method of fixed lead angle guidance (FLAG) trajectories of anti-torpedo torpedo was mainly introduced based on Matlab/Simulink. Based on the law of FLAG, the mathematical model of anti-torpedo torpedo guidance system was discussed. Then, the simulation model was designed with Simulink. Simulation shows that the intercepting trajectories of anti-torpedo torpedo based on FLAG has a higher interception probability, and increasing the velocity of anti-torpedo torpedo can reduce guidance time. Choosing appropriate fixed angle and launch angle can enhance the interception probability effectively.

Key words： MATLAB/Simulink; FLAG; trajectories simulation
