一种基于落角约束的偏置比例导引律

为增大反坦克导弹的命中落角，提高毁伤效果，建立了击顶弹道末制导段的弹目相对运动模型，提出了一种基于落角约束的偏置比例导引律，并研究了落角约束对导引律法向过载的影响，通过设计盲区控制方案减小了命中点法向过载，最后基于导引弹道仿真与传统比例导引律以及两种其它类型的改进比例导引律进行了仿真比较. 仿真结果表明，该偏置比例导引律控制落角能力较强，同时具有较高的命中精度. 

A Bias Proportional Navigation Guidance Law Based on Terminal Impact Angle Constraint

In order to increase the impact angle of upper armor attack trajectory and increase the damage effect of anti-tank missile, the missile-target relative motion model of terminal guidance phase was derived. A new guidance law called bias proportional navigation guidance law based on terminal impact angle constraint was proposed, the influence of impact angle constraint on normal overload was studied and a control scheme of blind area was designed to decrease the normal overload at hit point. At last, the new guidance law was compared with conventional proportional navigation guidance law and two other improved proportional navigation guidance law based on trajectory simulation. Results of the simulation show that the new guidance law has better effect on control impact angle and high impact accuracy.
