Research on Resolution of SDM Algorithm for Inverse Scattering Imaging

In this paper, the resolution of inverse scattering imaging based on the supervised descent method (SDM) is studied. The simulation model is mainly composed of eight half-wave dipole antennas. There is a cylindrical radiating boundary on the periphery of the eight antennas, and the imaging area is surrounded in the middle of the antenna, in which two small balls are placed as target objects. The resolution of inverse scattering imaging in this case is studied based on SDM algorithm by simulating the parameters of ball size, background conductivity and background permittivity. The preliminary results show that the resolution of inverse scattering imaging is affected by the size of the ball, the background conductivity and the background permittivity.
