Abstract:

The effects of simultaneous platform motion and antenna scanning are compensated for in radar systems of the moving-target-indicator type. Signals from auxiliary sub-arrays of the antenna compensate signals from main sub-arrays of the antenna for the effects of antenna scanning. Delayed, scanning-compensated signals from the main sub-arrays are then combined with undelayed, uncompensated signals from the main sub-arrays to provide signals that are compensated for the effects of scanning motion and platform motion. A first embodiment provides a clutter canceller having motion compensation at each stage of cancellation. A second embodiment provides a large number N of motion-compensated signals which are synchronized in time and phase for further MTI processing. Author
