摘要
A novel method for the joint parameters estimate in the bistatic multiple-input multiple-output (MIMO) radar system was proposed. Firstly, a novel signal model to accurately estimate parameters of the target was proposed. Two Doppler parameters, initial Doppler frequency and Doppler frequency rate, were estimated by peak-searching in the fractional Fourier transform (FRFT) domain. Two sub-array models to accurately estimated the direction of departure (DOD) and direction of arrival (DOA) by employing the proposed fractional Fourier transform based MUSIC (FRFT-MUSIC) algorithm and the fractional Fourier transform based ESPRIT (FRFT-ESPRIT) algorithm. Simulation results were presented to verify the effectiveness of the proposed method.
