A method generates a three-dimensional (3D) scene image of a scene using a MIMO array including a set of antenna by first selecting a subsets of the antennas as transmit antennas and receive antennas. Radio frequency (RF) signal are transmitted into the scene using the subset of transmit antennas while the MIMO array is moving at a varying velocity. The RF signal are received at the subset of receive antennas as MIMO data, which is aligned and regularized. Then, a compressive sensing (CS)-based reconstruction procedure is applied to the aligned MIMO data to generate the 3D image of the scene.
