摘　　要：现有的相控阵雷达搜索参数设计方法主要针对搜索波束驻留时间和搜索帧周期这两个参数。然而,对于相控阵雷达特殊的alert-confirm工作模式,由虚警引起的时间消耗,也是影响搜索性能的重要因素之一。研究了搜索波束驻留时间、搜索帧周期和虚警概率3个参数对搜索性能的影响,建立了相控阵雷达的搜索性能优化模型,并以此获得了最优搜索参数。最后通过仿真对比,验证了本文方法的有效性。The existing methods for optimizing search performance of phased array radar are mainly referred to two parameters,the dwell time of a search beam and the scan time.But for alert-confirm operation mode,the expending time resulting in false alarm is also a factor which affects search performance.The influence on search performance caused by the dwell time of a search beam,scan time and false alarm probability was analyzed,then the optimal operation parameters for search performance was designed.Compared with other methods,the simulation results show the validity of this method.
