1D scattering center extraction based on electromagnetic simulation data by improved TLS-ESPRIT algorithm

An improved LTS-ESPRIT algorithm is used to study the extraction of one-dimensional scattering center, in which the Hankel matrix is introduced to construct the measurement matrix to improve the accuracy of the method. The proposed method is used to extract target scattered echoes obtained by SBR technique, and the simulation results verify the feasibility and effectiveness of this method. Compared with the classical IFFT method, this method has a higher resolution unit, which can effectively identify dense scattering centers.
