摘　　要：针对大型相控阵雷达单元失效对性能指标影响难以有效评估量化的问题,设计了基于GUI的单元失效对性能指标影响仿真平台。首先,详细分析了大型相控阵雷达的结构特点与故障特点,将单元失效分为单元级随机失效、组件级随机失效和子阵级随机失效,建立了单元失效对性能指标(方向性系数、波束宽度和副瓣电平)的影响分析模型;然后,基于GUI设计了大型相控阵雷达性能指标影响仿真平台。仿真结果表明:该平台能够有效地呈现不同级别的单元失效对性能指标的影响程度,同时兼具直观形象和便于分析比较的优点,有利于提高装备维修效率和维修资源的优化配置。Aiming at the problem that it is difficult to evaluate and quantify the impact of large-scale phased array radar unit failure on performance indices,a simulation platform based on GUI was designed to simulate the impact of unit failure on performance indices.Firstly,the structure and fault characteristics of large-scale phased array radar were analyzed in detail,where unit failure was divided into unit level random failure,module level random failure and subarray level random failure,and thus an impact analysis model(array directivity,beam width and side lobe level)was established.Finally,a simulation platform for performance indices impact of large-scale phased array radar based on GUI was designed.The simulation results show that the platform can realize the impact of different levels of unit failure on performance indices,and is characterized by intuitive image and easy analysis and comparison,which is advantageous to improving equipment maintenance efficiency and optimizing allocation of maintenance and support resources.
