Abstract:

Based on the geometrical projection of 3D scattering centers on the line of radar sight, a new method of scattering centers association and 3D imaging of radar targets is proposed. The random sample consensus (RANSAC) method is utilized to examine the validity of the associated samples and select the optimal associated scheme of each scattering center. Simulation results show that the proposed algorithm, which has higher simplicity and robustness, is applicable for the cases with more scattering centers and numbers of attitude, and is able to be applied in the association and 3D imaging for scattering centers existing missing and fault points.
