摘要：

A novel method for three-dimensional (3D) imaging by combining a narrowband bistatic multiple-input multiple-output (MIMO) radar with two uniform linear arrays and inverse synthetic aperture technique is presented. During a short coherent processing interval (CPI), the motion of the target can be equivalent to a synthetic uniform linear array, which, together with the two narrowband MIMO arrays, is capable to reconstruct the 3D image of the target. Compared with the one snapshot narrowband MIMO 3D imaging using two rectangular arrays, the proposed method can achieve a significant saving on the number of antennas since the linear arrays and multiple snapshot technique are employed. Considering the low resolution of the image via limited MIMO arrays, a compressive sensing (CS)-based method is proposed to improve the 3D resolution jointly. Finally, simulation results demonstrate the proposed method is effective.
