An MIMO-MTI approach for through-the-wall radar imaging applications.
In this paper, we apply Multiple-Input Multiple- Output (MIMO) configurations to Moving Target Identification (MTI) for urban sensing using radars. In particular, we consider MIMO-MTI formulations for detecting slow-moving personnel inside enclosed structures and behind walls. Using signal multiplexing from two transmitters and several receiver positions, it is shown that the virtual array (co-array) implementing MIMO schemes, applied to stepped-frequency radars, permit improvement in image resolution of moving targets. Laboratory experiments are conducted to validate the proposed approach with targets walking behind walls.
