Azimuth multi-channel interferometric SAR (AMC-InSAR) mode integrates the azimuth multichannel high-resolution wide swath (HRWS) imaging technique and high-precision InSAR digital elevation model (DEM) generation technique. More equivalent phase centres are obtained through the azimuth single-input and multiple-output technique, which would provide more azimuth samples. Hence, the reliable and accurate DEM measurement of more wide-swath terrain profile would be obtained. Here, the performance of this AMC-InSAR mode is evaluated theoretically. A new processing method based on measured data for this mode is provided and the results of measured data-processing validate the analysed results and the new method.
