Abstract

This paper presents a novel method for joint parameter estimation of multiple targets for bistatic multiple-input multiple-output radar system in impulsive noise. Firstly, a new signal array model is constructed according to a 3-D motion characteristics of target in impulsive noise environment. Secondly, Doppler frequency parameters are jointly estimated by peak searching of a fractional lower-order ambiguity function based on fractional Fourier transform (FLOS-FAF) and a dechirping method. Furthermore, two modified algorithms are proposed for the estimation of direction-of-departure and direction-of-arrival, including the MUSIC algorithm based on the fractional lower-order ambiguity function (FF-MUSIC) and the ESPRIT algorithm based on the fractional lower-order ambiguity function (FF-ESPRIT) in the fractional Fourier transform domain. Simulation results are presented to verify the effectiveness of the proposed method.
