TLS-ESPRIT Multiband Fusion Processing Based on Hankel Matrix Improvement
In view of the shortcomings of traditional matrix pencil algorithm in estimating the parameters of all-pole model under the condition of low signal-to-noise ratiothe calculated values are unstable and the accuracy of pole estimation is not high.FirstlyHankel matrix is introduced into the echo signal for signal decoherencethen the improved TLS-ESPRIT algorithm is used to estimate the poles of multi-band signalsand the improved TLS-ESPRIT based on Hankel matrix replaces the traditional matrix pencil to calculate the parameters of full-band all-pole modelso as to improve the accuracy of the fused signal.The final simulation and measured data show that the proposed method improves the fusion performance of multi-band signals at low SNR.
