A new algorithm to jointly estimate the DOD-DOA and Doppler parameters of bistatic multiple-input multiple-output(MIMO)radar is proposed based on the fractional power spectrum density.For moving target
the echo often contains time-varied Doppler frequency.A new signal array model of bistatic MIMO radar system is constructed in this paper.Doppler parameters are estimated by searching the peak of fractional power spectrum density(FPSD).Two subarrays are constructed based on FPSD.Both direction of departures(DODs)and direction of arrivals(DOAs)of the multiple targets are estimated by employing the FPSD-MUSIC algorithm and FPSD-ESPRIT algorithm.Furthermore
the Cramr-Rao bound(CRB)for target parameters estimation is derived.Simulation results are presented to verify the effectiveness of the proposed method.
