摘要
角反射体雷达散射截面(RCS)的测量是雷达目标识别、成像等研究领域的一个关键环节;在对目标RCS测量原理分析的基础上,介绍了一个在微波暗室中基于紧缩场和矢量网络分析仪测量目标RCS的测量系统;利用该系统对角反射体垂直姿态和45°姿态的RCS进行了360度转角扫频的测量,结果与FEKO软件仿真计算的结果对比表明,两种方法得到的数据走势基本一致。
Corner reflector＇s radar cross section measurement is important in many fields,such as radar target recognition and radar imaging.Based on the principle of target＇s RCS measurement,a measurement system in microwave anechoic chamber is presented.The measurement system mainly takes advantage of the CATR and vector network analyzer.With this system,the vertical and 45°attitude of the corner reflector＇s RCS is measured in sweep frequency of 360 degree.Compared with the result calculated by FEKO simulation software,the trend of the data got by two methods is almost consistent.
