| 摘 要： | 为改善拦截导弹战斗部毁伤威力,针对其碰撞角度约束问题进行了研究。采用终端投影变换进行系统降阶,并基于线性二次型性能指标,推导了一种考虑碰撞角度约束的微分对策制导律。对其制导增益、鞍点解的存在条件和理想拦截性能进行了研究。制导律的推导基于最坏目标机动情形,不受限于具体的目标机动形式,尤其适用于目标机动无法预测的拦截情形。非线性系统仿真表明当拦截导弹具有足够的机动性能时,即使目标机动或存在一定的指向误差,该制导律的脱靶量和碰撞角误差仍约为0。

| Abstract: | To improve the interceptor ' s warhead lethality,the impact angle constraint of the interceptor is researched.Terminal projection transformation is used to reduce the problem ' s order and a differential game guidance law with impact angle constraint is derived based on a linear quadratic cost function.The guidance gains,the existence of a saddle point solution and the performance of perfect interception are researched.The derivation of this guidance law considers the worst-case target maneuver,so it is not... |
