Abstract
A method for discrimination of a target from clutter, comprising: providing phase-range data associated with a return pulse of a radar device and second phase-range data associated with a subsequent return pulse; comparing the phase-range data and the second phase-range data to obtain a difference; differentiating the differences with respect to range; and discriminating the target from the clutter by identifying coordinates from the differentiated differences satisfying velocity thresholds associated with the clutter. In one embodiment, the subsequent return pulse is drawn after skipping one or more pulses after the return pulse. In another embodiment, the subsequent return pulse is drawn successive to the return pulse. In other aspects, the invention can be a detection system and/or computer-readable medium adapted implement the method.
