Abstract
A method for suppressing clutter when detecting objects of interest in a radar system is provided. The method includes defining a plurality of scatterer classes corresponding to a plurality of predetermined scatterer motion types, at least one of the classes corresponding to ballistic acceleration, and at least one of the classes corresponding to non-ballistic acceleration. A plurality of sensor pulses are transmitted, and reflected return pulses are received. Scatterers identified in the radar return signal are associated with one of the scatterer classes. A set of complex weights is generated and applied to the radar return signal data to null scatterers associated with the class corresponding to ballistic acceleration.
