摘要This paper presents a multi-input-multi-output (MIMO) range migration algorithm (RMA) with range compensation for near-field millimeter-wave imaging. The proposed algorithm is derived based on the effective phase center principle and scalar diffraction theory. Compared with the original MIMO RMA, the propagation loss is compensated better, and the reconstructed image quality is improved significantly. In the process of image reconstruction, a multistatic array topology is transformed to a monostatic array, and the round-trip propagation is converted into unidirectional optical field propagation. The efficiency of the proposed algorithm is analyzed theoretically, and demonstrated experimentally. Numerical simulations and experimental results show that the propagation loss in range is properly compensated by the proposed algorithm.
