Theoretical assessment of MIMO radar performance in the presence of discrete and distributed clutter

We consider mitigation of clutter that is distributed in range and Doppler frequency for scenarios that have a difference in the direction-of-departure (DoD) between a target and a clutter patch at the same radar range. We demonstrate that efficient clutter mitigation can be achieved by a MIMO radar with a specific waveform set by (adaptive) non-causal beamforming of the transmit antenna under certain limitations on the total area in range and Doppler frequency occupied by all possible targets and clutter.
