Abstract:
For fast parameter extraction of target scattering centers in optical region,this paper proposes to use a mini-norm method based on eigenvalue decomposition or propagation factor to improve parameter estimation efficiency of scattering centers.The mini-norm method based on eigenvalue decomposition can decrease computational loads and achieve estimation performances similar to the multiple signal classification algorithm,which works even when SNR is low.The propagation factor method is faster than eigenvalue decomposition method and the mini-norm method based on propagation factor is more effective with high SNR.Simulation results show that the proposed algorithm can improve parameter estimation efficiency and keep parameter estimation accurate.
