Abstract
The performance of ground-moving target indicator radars is often degraded in complex terrain by multipath spread-Doppler clutter. Multiple-input, multiple-output (MIMO) beamforming with limited training data has been previously proposed with separable transmit and receive weights appropriate for discrete multipath scenarios. In this paper, partially adaptive MIMO beamforming is presented for suppression of a nonseparable continuum of multipath clutter with limited training data. Simulation results for a forward-looking vehicle-mounted radar in a simplified urban environment are described.
