基于ESPRIT的高分辨率时延估计算法研究

ESPRIT algorithm is used to estimate the angle of arrival (DOA) of the super-resolution algorithm.This algorithm has a very outstanding performance in both effectiveness and stability.Therefore, based on the ESPRIT algorithm made many improvements and become a major super-resolution algorithm.Based on the ESPRIT algorithm theory,it proposed that the ESPRIT algorithm estimates the signal arrival time (TOA).Algorithm used in two ways: one is the least-squares algorithm, one is the total least squares algorithm .Proved by simulation: in low SNR, the total least squares algorithm performs better than least squares algorithm, but requires the large calculation.
