摘要：

针对无人战机(unmanned combat air vehicles,UCAV)(目标)发射防御弹对来袭攻击弹以一定拦截角度进行拦截的问题,假设目标和防御弹协同飞行且其之间只能进行单向信息传输,在来袭弹采用增强比例导引律的前提下,建立了防御弹信息单向传输和目标信息单向传输两种模式下的防御弹攻击弹视线角非线性模型。考虑防御弹脱靶量要求、拦截角度约束和防御弹(或目标)的控制能量因素,建立了性能指标函数,采用最优控制理论,分别设计了能够使防御弹以指定拦截角度拦截攻击弹的目标单向协同制导律和防御弹单向协同制导律。仿真结果表明,在两种信息单向传输模式下,通过目标与防御弹的协同,防御弹均可以指定拦截角拦截攻击弹;与具有拦截角度约束的非协同制导律相比,单向协同制导律的控制能量更小。

Abstract:

The issue of intercepting an incoming missile (attacker) with a certain intercept angle by a defensive missile (defender) launched from an unmanned combat air vehicle (UCAV) (target) is considered. Assuming the attacker adopts the augmented proportional navigation law and there is one way information transportation between the defender and the target, the nonlinear model describing the changing of the line of sight between the defender and the attacker is derived. With the consideration of the requirement of the defender’s miss distance, the constraint of defender’s terminal intercept angle and the control energy of the defender (or target), the performance index is established. The one way cooperative guidance law of the target and that of the defender, which can make the defender intercept the attacker with the designated intercept angle successfully, are deduced based on optimal control theory. Simulation results show that the defender can intercept the attacker with a designated intercept angle through the cooperative flight with the target under two kinds of oneway information transmission. The control energy under the one way cooperative guidance law of the defender is less compared with that under the non-cooperation guidance law.

Key words: defender, attacker, one way information transmission, intercept angle constraint, cooperative intercept guidance law
