SAR校准常用参考目标分析和比较

Analysis and Comparison of SAR Calibration

从合成孔径雷达(SAR)校准的基本原理出发,对SAR校准参考目标的一般特性要求进行了归纳总结。着重分析常用的无源角反射器和有源雷达校准器(ARC)的构造和电磁特性,并对它们的优缺点进行了比较。指出ARC是从性能来讲最理想的SAR校准参考目标。

General character requirements of SAR calibrators is summarised based on the SAR calibration theory .Then, the electricmegnetic characters of both passive radar calibrator and active radar calibrator (ARC) are analysised and comparised.It's pointed out that ARC is the best SAR calibrator.
