High-order moments modeling algorithm of radar target impulse response

Abstract

A method for characterizing radar signatures using HOMM (high-order moments modelling) is developed based on the high-order moments theory. This method consists of extracting radar target natural resonant frequencies by estimating the model of the radar target impulse response. In this paper,we analysed UWB radar target impulse response using high-order moments character on the base of the singularity expanding method, and made use of the total least squares method coupled with singularity value decomposition to accurately estimate the parameters of a rational of the impulse response.<>
