Three-Dimensional Reconstruction Using Polarization in Passive Millimeter-Wave Imaging

Passive millimeter-wave (PMMW) polarization imaging is an important method for target detection. The three-dimensional (3-D) reconstruction technique can realize the surface shape recovery of the target detected by the millimeter-wave radiometer. This paper presents a method for 3-D reconstruction using single-station millimeter-wave polarization imaging. The incidence and azimuth angles of normal vectors are inverted by polarization degree and polarization angle parameters. The 3-D structure is reconstructed using the neighborhood correlation property. Simulation experiments for spherical and face targets verify the effectiveness of the proposed method.
