MIMO Radar Near-Field 3-D Imaging Algorithm in Frequency Domain

Near-field 3-D radar imaging is widely used in areas such as disaster rescue, airport security and urban warfare. This paper proposed a 3-D imaging method for cross-shaped array and square-shaped array in frequency domain. Firstly, the virtual aperture frequency domain imaging algorithm is introduced, then for cross-shaped array and square-shaped array, 3-D imaging method were studied, Finally, the correctness and effectiveness of the proposed approach were verified with FDTD simulation.
