The Modeling and Simulation of A near-distance microwave imaging system

For the purpose of diagnosing the scattering points of radar target exactly, a near-distance microwave imaging system is designed. The theoretical equation of imaging can be gained by mathematical model with cooperation object. Imaging equation can be solved by spherical wave filter back projection arithmetic quickly. The simulation result show that good performance 2D image with high resolution can be obtained by utilizing spherical filter back projection arithmetic, which can digest the scattering points exactly and in detail.
