摘　　要：针对现代作战环境不仅希望反坦克导弹脱靶量最小,还希望导弹命中目标时姿态最佳的问题,对传统比例导引律和带落角约束的比例导引律进行了研究,并提出了带有碰撞角约束的三维比例导引律,即在俯仰通道采用带落角约束的比例导引,在偏航通道采用传统比例导引。最后以某型自寻的反坦克导弹制导控制系统的设计为背景,通过结合导弹总体参数,建立弹体运动数学模型、制导控制系统模型、舵机模型等,并利用Simulink对其进行了仿真。仿真表明,2种导引律结合运算的方法不仅易于实现,而且具有精度高、落角变化范围大,过载小的优点。In order to decrease miss distance and to meet the demand of impact angle, the classical proportional navigation law and proportional navigation with terminal angular constraint in 2D is investiga- ted and a three-dimensional proportional navigation with terminal angular constraint is proposed. Finally in the back ground of guidance and control system of a homing guidance antitank missile, the data of the missile are combined to build mathematical model of missile movement, guidance control system model, rudder model, etc. and the models are simulated with Simulink. The results show that the guidance is not only easy to implement, but also has high accuracy, low overload, and high terminal angular.
