Abstract

Abstract

A new program-controlled initial trajectory allowing an anti-torpedo torpedo(ATT) to find the incoming torpedo quickly and achieve rapid occupation was investigated in this study. A virtual target was introduced according to the target motion characteristics, and a bias proportional guidance law considering the terminal angle constraint was designed. The virtual target led the ATT to the real target according to the designed guidance law. Simulation results indicated that in a typical situation of an ATT intercepting incoming torpedoes, the introduced virtual target and the bias proportional guidance law designed for the ATT can help the ATT quickly detect incoming torpedoes. They can significantly increase the interception probability of ATTs and thus enhance the battlefield survivability of submarines.
