摘　　要：为使反鱼雷鱼雷(ATT)快速发现来袭鱼雷,实现快速占位,研究了一种新的最佳导引弹道,利用目标运动特性信息引入虚拟目标,设计了考虑终端角约束的偏置比例导引律,以此虚拟目标将ATT按设计的导引律引向真实目标。仿真结果表明,在典型ATT拦截来袭鱼雷态势下,引入虚拟目标设计的偏置比例导引律能够使ATT快速发现来袭鱼雷,有效提高ATT的拦截概率和潜艇的战场生存能力。A new program-controlled initial trajectory allowing an anti-torpedo torpedo(ATT)to find the incoming torpedoquickly and achieve rapid occupation was investigated in this study.A virtual target was introduced according to the targetmotion characteristics,and a bias proportional guidance law considering the terminal angle constraint was designed.Thevirtual target led the ATT to the real target according to the designed guidance law.Simulation results indicated that in atypical situation of an ATT intercepting incoming torpedoes,the introduced virtual target and the bias proportional guidancelaw designed for the ATT can help the ATT quickly detect incoming torpedoes.They can significantly increase theinterception probability of ATTs and thus enhance the battlefield survivability of submarines.
