摘要: 星载合成孔径雷达(SAR)系统需要对收发通道相位稳定性进行测试，以评估系统成像性能。该文基于少量设备，结合FFT 变换、匹配滤波和插值处理，给出了两种星载SAR 系统收发通道相位稳定性测试方法，以实现SAR 收发通道相位稳定性高精度测试，并对两种方法的测试结果进行比较。某型号星载SAR 模样机系统实际测试结果验证了上述方法的可行性和有效性。

Abstract: Accurate phase stability measurement of Transmitting and Receiving channels in space-borne SAR (Synthetic Aperture Radar) system is important to evaluate imaging quality. Based on fewer instruments, matched filtering and interpolation algorithm, two kinds of measure methods which makes the measurement value more accurate are presented and compared in this paper. The test result of one space-borne SAR prototyping system indicates that the methods are feasible and effective.
