Ultra-wideband high-resolution three-dimensional imaging method

Two-dimensional Multiple Input Multiple Output (MIMO) array can form the high-resolution three-dimensional (3D) image of the near-filed target, Azimuth resolution of 3D imaging depends on angle of antennas and targets. The further distance between arrays is, the worse result of azimuth resolution we get. In this paper, we propose a method based on highresolution 3D imaging of depth compensation, which makes resolution of target in different ranges same. The effect of parameter in depth compensation is discussed. Finite-difference time-domain (FDTD) simulation results validated the proposed method.
