摘　　要：波束以及系统参数的捷变能力使得多功能相控阵雷达能够同时对空域中的多个区域分别采用特定的搜索模式进行搜索。用于搜索的雷达资源会随着跟踪等高优先级的任务对资源消耗的变化而变化。因此,需要动态地调整可获得的搜索资源在各个搜索子空域中的分配以优化整个系统的搜索性能。首先建立了多功能相控阵雷达的搜索性能评估模型,得到了搜索性能及其增益与搜索参数的关系。而后针对搜索负载的动态变化,建立了相控阵雷达同时多区域搜索资源分配的优化模型,并通过仿真验证了模型的有效性。The agility of the beam and the system parameters offers multifunction phased array radar the ability to simultaneously search in multiple volumes with specified search mode respectively. The search resource is to change with the resources occupied by the missions with higher priority such as tracking. It is necessary to allocate the acquired search resource to the sub-volumes dynamically to optimize the search performance of the system. The evaluation of the search performance of the multifunction phased array was first modeled and the relation of the search load and the search performance as well as the search performance gain was derived. Then for the dynamic change of the search load, the optimization of the allocation of the search resource to multiple sub-volumes was modeled and the model was validated through simulation.
