Scattering centers association and radar imaging based on multi-aspect measures

Radar imaging is an important way to obtain the structural information of target. Based on the geometrical projection of scattering center on the line of radar sight, the principle of reconstructing scattering centers´ 3-D distribution based on multi-aspect measures is provided in this paper. After analyzing the characteristic differences between true and false scattering centers, the multiple elastic modules (MEM) is introduced to perform scattering centers association and radar target imaging. The experiments are developed with simulated and experimental data, and experimental results show the feasibility and validity of proposed approach.
