摘要
RCS测量雷达在宽频带对目标进行RCS测量时,为了能得到准确目标的RCS值,必须对雷达系统进行标定。将气球悬挂标准金属球作为标准定标体,气球的RCS、定标球的加工误差对标定结果有较大影响。进行了误差分析,并提出改进措施,以提高RCS测量雷达系统的校准精度。
In order to get the RCS of the accurate target, when RCS measurement radar is measuring the RCS of the target in the broadband ,it must calibrate toward radar system. Takes the standard metal ball that flies balloons as the standard calibration body, the balloon RCS, processing error of calibration body have more influence on the calibratiion result. This paper analyzes the error,presents improvement measure,in order to raise the calibration precision of RCS measurement radar.
