信号级协同雷达组网在对抗条件下发挥着越来越重要的作用。针对三部雷达信号级协同搜索场景下有限雷达资源的分配问题,从单部雷达资源分配策略出发,确定了信号级协同搜索资源分配的时空约束条件,分析了三部雷达满足信号级协同搜索约束的几何构型及其判定方法,推导了每种几何构型下的协同搜索区域面积计算方法,建立了协同搜索优化 模型及基于遗传算法的协同资源分配流程,最后设置典型场景进行了仿真。仿真结果表明,雷达性能越好,分配给协同辐射的雷达资源越少,对实际的雷达信号级协同搜索应用具有指导意义。

Signal-level cooperative radar networking has been playing an increasingly important role under adversarial condition.Aiming at the problem of resource allocation of limited radar resources in the signal-level cooperative search scenario of three radars,a method of search resource allocation is proposed to maximize the detection range of signal-level cooperative radars. Starting from the search resource adjustment strategy for a single radar, the time-space constraint conditions, geometric configuration and judgment method of signal-level cooperative search resource adjustment are analyzed. For the scene of cooperative detection of three radars, the calculation method for collaborative search area under each geometric configuration is deduced. An optimization model for collaborative search and a collaborative resource allocation process based on genetic algorithm are established. Finally, simulation results for typical scenarios verify that the radar with better performance needs the less cooperative resource. The result is of certain significance for practical application of radar signal-level cooperative search.
