一种能实现超前偏置的比例导引律

A Proportional Navigation Law for Improving Target-Finding Accuracy to Very Small Tactical Missile

文中提出了一种能实现超前偏置的比例导引律,运动学分析和动力学仿真的结果表明:采用此种比例导引律后,能提高红外寻的导弹的命中精度.与根据最优理论获得的导引律相比,实施比较方便,只需在导弹的发射架(简)上安装一陀螺即可,无需计算导弹的剩余飞行时间.

In order to help Chinese infantry men to deal effectively with air attack,it is necessary to improve asmuch as possible the target-finding accuracy of very small tactical missile.Guidance law =K-K_1(/τ~2) is well known.It can enable the missile launched to obtain thesetover of lead needed for hitting the target,but the calculator in the missile needs to computecontinuously“time to go”.In this paper another guidance law =ak(eq.5 in the full paper) is proposedthat makes the computation of“time to go”unnecessary.Kinematics analysis and dynamics digital simulation indicate that the proposed law can improve con-siderably the target-finding accuracy of very small tactical missile.
