摘　　要：针对临近空间高超声速滑翔目标防御中存在目标机动能力强、机动意图不明确的问题,提出一种基于可达区在线预测的滑翔段拦截器(GPI)中制导协同拦截策略。基于滑翔弹道解析解给出针对目标横程机动的可达区在线预测方法。利用多项式拟合和反向传播(BP)神经网络给出GPI标控弹道的纵程可达区在线预测方法,并利用弹道解析解进一步给出拦截弹的横程可达区在线预测方法。通过对目标和拦截弹可达区在线预测,引入多弹协同思想,实现拦截弹可达区对目标可达区的覆盖,完成协同拦截策略的设计。拦截仿真分析表明:所提协同拦截策略可有效应对目标的倾侧反转机动。To address the challenges of intercepting a hypersonic glide target in near space with significant maneuverability but ambiguous maneuver intention,this paper proposes a cooperative interception strategy for the midcourse guidance phase of a gliding phase interceptor(GPI),based on online prediction of an accessible area.First,based on the analytical solution of gliding trajectory,the online estimation method of lateral reach area is given.Next,polynomial fitting and back propagation(BP)neural network are used to offer an online strategy for GPI that predicts the area of reachable range under normal effort.The analytical solution is used to estimate the lateral reachable area.Finally,the interception arc and firing data can be determined under the concept of cooperative interception.Interception simulation and analysis verify that the cooperative interception strategy can effectively deal with the reversal maneuver of a hypersonic gliding target.
