Summary:
Near range three-dimensional (3D) microwave imaging techniques have broad application prospects in the field of concealed weapon detection, biomedical imaging, nondestructive testing, etc. In this paper, the technique of optimized sparse antenna array is applied to near range 3D microwave imaging, which can greatly reduce the complexity of imaging systems. In detail, the 3D sparse antenna array imaging geometry and corresponding echo model are established in this paper. Then, the paper deduces the BP algorithm applied to 3D sparse array geometry. After that, the imaging geometry and imaging algorithm are investigated and verified by means of near range microwave imaging experiment.
