面向临近空间目标拦截的预测命中点设计方法

针对基于吸气式高超声速平台的临近空间目标拦截概念方案,考虑由于吸气式动力拦截平台飞行策略与火箭动力拦截弹的区别,导致传统预测命中点设计方法不适用的问题,开展面向吸气式高超声速平台的拦截预测命中点设计方法研究。首先,基于拦截空域最大的原则,结合吸气式动力飞行策略构建高超声速拦截平台的标准弹道族;然后通过将多约束拦截预测命中点设计问题分解为基于航程约束的拦截时间迭代计算问题和满足高度约束的拦截点的高效筛选问题,快速完成预测命中点规划。最后,通过仿真实验说明了提出的面向吸气式高超声速拦截平台预测命中点规划方法的有效性。

Method of Predicted Impact Point Planning for Near Space Target Interception

The conceptual scheme of target interception in near space based on air breathing hypersonic platform is proposed. Considering that the flight strategy of an air breathing interceptor platform is different from that of a rocket power interceptor, the traditional design method for the planning of predicted impact point is not applicable. Thus, the research on the design method for the planning of predicted impact point for air breathing hypersonic platform is carried out. Firstly, based on the principle of maximum intercepting airspace, the nominal trajectories of hypersonic intercepting platform are constructed by combining with the air breathing dynamic flight strategy. Then, the problem of iterative intercept points satisfying the multiple constraints is transformed into the problem of iterative intercept time based on the range constraints and the process of filtering out the intercept points that meet the high constraint. Finally, the simulation results show the effectiveness of the proposed predicted impact point planning method for an air breathing hypersonic interception platform.
