2021 3 SPACE ELECTRONIC TECHNOLOGY . In this paper, a three-channel SAR / GMTI method based on Dechirp SAR imaging technology is used to detect,
locate the ground moving targets and measure the velocity of them. This paper focuses on a method that combines phase
compensation, image registration and multi-channel multi-pixel adaptive processing Clutter suppression. In the presence and
absence of registration errors, the clutter suppression results of adaptive processing and direct methods are compared, which
shows that the adaptive processing is more robust than the direct method against registration errors. The feasibility is verified
by processing the measured data of the three-channel SAR / GMTI system.
