Two dimensional scattering center extraction and analysis of radar targets

In this paper, we estimate the scattering center parameters of radar targets from measured data to analyze the scattering characteristics of the target. Some improvements are made in order to estimate the parameters accurately. Firstly, we use the interpolation method to solve problems such as range migration caused by the large synchronized imaging aperture, and obtain the signal model after interpolation. Secondly, we use diagonal loading technology to greatly improve the order selection criterion for measured data. Then we use 2D-ESPRIT algorithm to deal with the measured data of a missile, and analyze the characteristics of the missile from the experimental results.
