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.
