摘　　要：针对多个拦截弹协同拦截单个机动目标的情况,提出了一种范数型的协同微分对策制导律。在拦截弹和目标的控制系统均具有理想动力学特性且法向加速度均有界的条件下,对追逃对策问题进行分析,建立了线性化的多对一追逃对策运动模型,基于微分对策理论选取范数型的性能指标,推导得出了一种具有"bang-bang"结构的最优制导策略。上述制导律无需预先对目标的机动规律做假设,且可避免出现因加速度饱和而导致制导律失去最优性的现象。最后通过对拦截多种机动形式的目标进行仿真,验证了上述方法的有效性。For the problem of intercepting a single maneuvering target by multi-interceptor,a cooperative norm differential games(CNDG)guidance law is proposed.It was assumed in this paper that both interceptors and target have ideal dynamics,and bounded normal accelerations were also taken into account.Linear many-on-one pursuit-evasion model was constructed,and a cooperative norm guidance law that has a form of"bang-bang"structure was derived.There is no need to make any assumption of target maneuver,and the loss of optimality due to acceleration saturation was avoided.Simulations are used to validate the guidance law proposed,through intercepting a variety of target maneuvers.
