Near-Field Imaging Analysis of Three-Dimensional MIMO Array

This paper presents a MIMO imaging system, which has good imaging effect and higher resolution. The equations for the position of antennas are deduced in detail. The proposed algorithm is used to carry out inverse scattering microwave image through the near-field scattered electric field which is obtained by the simulation software. The formulas of imaging resolution of MIMO antenna array are presented in this paper. The main factors which influence the quality of the image are analyzed, and the accuracy and feasibility of the resolution formula are verified by the simulation of complex object, which provides a valuable reference method for the actual microwave imaging system.
