数字阵雷达阵面微波暗室测试时,阵面数据异常会影响阵面数字波束合成及天线方向图特性,且定位困难,影响天线测试效率.在分析阵面数据组成结构的基础上,设计了数据融合软件,对错误数据包进行解析,生成新的可用数据包,补充了阵面测试系统的容错能力.通过对阵面数据流程分析,选择关键节点,自制光纤接口转换设备,简化排故路径从而实现故障快速定位.,While digital radar array in microwave chamber is testing,wrong data from array can influence digital beam formed of array and diagram characteristics of antenna.In addition,quick and precise location can’t be realized.On the basis of analysis for data consistence and structure,a kind of data fusion software is introduced to analyze fault data package and generate usable new one,which strengthens fault-toleration ability of array test system.By process analysis of array data,key points selection,fiber interface conversion equipment making,and failure path simplification,fast failure location is realized.
