一种测量雷达散射截面参数现场校准方法

摘要

雷达散射截面参数是测量雷达一项非常重要的技术指标, 该参数的准确性直接影响雷达对被测目标隐身能力的判定.基于雷达散射截面参数有源定标技术、高精度雷达散射截面模拟控制技术、高稳定雷达散射截面回波信号合成技术等, 实现对雷达散射截面参数的动态精确模拟, 从而对测量雷达散射截面参数进行校准, 通过外场条件下的量值传递, 解决了测量雷达散射截面参数有源定标问题.%Radar Cross-Section (RCS) parameter is a very important technical standard of Instrumentation Radar.The parameter accuracy well directly affects the radar's determination of the stealthy ability of the measured target. Based on RCS parameter active calibration technology, high precision RCS parameter simulation control technology, high stability RCS echo signal synthesis technology, the dynamic and accurate simulation of RCS parameter is realized, The RCS parameter of the instrumentation Radar is calibrated. It is transfer value under the external field condition, the problem of active calibration of radar RCS parameter is solved.
