摘要：
In through-the-wall imaging, wall reflections are so strong that targets behind walls are usually obscured and invisible in the image, which severely affects the detection and further processing. Aimed at the wall clutter mitigation problems in through-the-wall MIMO radar application, the information of the signal characteristics and antennas' geometric relationship is deeply analyzed and optimally used. Based on this information, two variables "dealing signal" and "reference signal" are defined. Then a wall clutter method is proposed and its algorithm flow is given. The method can be efficient to mitigate the wall clutter and easy to realize. Full numerical electromagnetic simulations validate the efficiency of the method.
