1. A method for generating a three-dimensional (3D) image of a scene using a MIMO array including a set of antennas, comprising steps of:
- selecting at least one subset of the antennas as a subset of transmit antennas and a subset of receive antennas;
transmitting radio frequency (RF) signal into the scene using the subset of transmit antennas while the MIMO array is moving at a varying velocity;
receiving the RF signal reflected by the scene at the subset of receive antennas as MIMO data;
aligning and regularizing the MIMO data;
applying a compressive sensing (CS)-based reconstruction procedure to the aligned MIMO data to generate the 3D image of the scene.

Abstract
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.
