摘　　要：为实现反坦克导弹以较大落角攻击目标,提高导弹毁伤效率,结合落角约束与过载约束提出一种寻初比例导引法。首先建立落角预测模型,得出影响落角的参数;其次,结合导弹过载约束计算比例系数范围;最后,将落角预测模型与适当的比例系数相结合,得出满足战技指标的初值,实现导弹以较大落角命中目标。通过仿真结果表明该设计方法的正确性。In order to make the anti-tank missile attack the target at a larger impact angle,to improving missile damage efficiency,A new proportional navigation method combining angle constraint and overload constraint is proposed.First,setting up the prediction model of impact angle,obtain the factors that affect the impact angle;Then,the range of proportional coefficients is calculated with missile overload constraint;Finally,the prediction model is combined with appropriate proportional coefficient,obtain the initial value that satisfies the tactical index,and realize the missile hitting the target at a larger angle of attack.The simulation results show the correctness of the design method.
