THE EFFECT OF INTERCEPTOR'S DYNAMIC SYSTEM ORDER ON THE PENETRATION EFFICIENCY OF WEAVING MANEUVER STRATEGY

研究导弹动力学特性对导弹摆动式机动突防策略突防效果的影响 ,在研究策略自身突防效果的同时 ,着重分析了拦截导弹不同动力学特性的突防效果。突防拦截问题表述为拦截平面内线化变系数微分方程 ,它是变系数终值控制问题。适合此类问题的共轭系统分析法 ,用来求解导弹摆动式突防策略引起的拦截脱靶量的解析解。此解与拦截导弹动力学特性的等效时间常数、阶次及突防摆动持续时间、幅值、周期有关。

The influence of missile's dynamics on the penetration efficiency of weaving maneuver strategy is studied.In studying the penetration effect of the penetration strategy,the analysis of penetration efficiency for different interceptor's dynamics is emphasized.The penetration interception problem is expressed as a set of linearized differential equations with time variant coefficients in the intercept plane,which is time variant coefficient terminal control problem.The adjoint system analysis method,which is adaptive to the terminal guidance problem,is used to obtain the analysis solution of the interceptor's miss distance induced by the weaving penetration strategy.This solution is related to the equivalent time constant,the dynamics order of the interceptor's guidance system and the duration,the amplitude and the circle of the weaving strategy.Among them the dynamics order of interceptor's guidance system is the key factor that influences on penetration efficiency of the penetration missiles.
