摘　　要：针对预警机引导信息下相控阵雷达的最优搜索问题进行了研究。从预警机引导战斗机雷达搜索的角度出发,将搜索目标进行分类,根据实际作战需求加入搜索约束条件,完善现有的雷达最优搜索模型,提出两步优化策略来解决不同搜索阶段的优化问题;采用凸优化的手段对搜索模型进行求解,提出拉格朗日结合障碍法的方法来实现搜索数据率的快速优化,解决了雷达最优搜索多约束、多目标优化实时求解的问题,具有较高的工程应用价值;最后通过仿真验证了拉格朗日结合障碍法进行优化模型求解的有效性以及最优搜索模型的合理性。The optimal search problem of phased array radar based on early warning aircraft guidance is researched in this paper.The targets are classified from the perspective of fighter radar search based on the early warning aircraft guidance.In order to improve the existing radar optimal search model,new search constraints based on the actual combat requirements are proposed.And a two-step optimization strategy is presented to resolve the optimization problems in different search stages.The method of convex optimization is used to solve the optimal search model.Lagrange method combined with barrier method is proposed to solve the multi-constraint and multi-objective problem in real-time,which has greater engineering application value.Finally,simulation is used to verify the validity of the method.
