In this letter, the impact of antenna polarization configuration and polarization diversity on the imaging quality of a near-field microwave imaging system is examined. Unlike previous works, this study also develops an efficient alternating minimization approach for solving the relevant nonlinear inverse imaging problem with total variation regularization. By decomposing the problem into two simpler subproblems, this approach enables faster image reconstruction with less computational complexity. Using the developed approach, the effectiveness of various antenna polarization configurations is analyzed for application in brain imaging. The outcomes hold considerable practical significance, as they highlight the potential of polarization diversity to enhance image quality for applications where the space for antenna placement is limited.
