ABSTRACT:
The effects of platform motion or antenna scanning in radar systems of the oving-target-indicator type are compensated for by arrangements which use difference-channel signals to correct sum-channel signals for the changes in phase and amplitude of the backscattered sum-channel signals due to the platform motion and antenna scanning, respectively. Clutter-canceller arrangements having motion compensation at each stage of cancellation and an arrangement for providing a large number (N) of motion-compensated signals which are synchronized in time and phase are shown.
