Joint Angle, Range and Velocity Estimation for bi-static FDA-MIMO Radar
It is known that there is a contradiction between high-resolution range estimation and velocity estimation due to the influence of pulse repetition frequency(PRF)in traditional phased-array(PA)radar.In this paper,a joint unambiguous angle,range and velocity estimation method is proposed for bi-static multiple-input-multiple-output(MIMO)radar with frequency diverse array(FDA).Owing to the FDA,there is a little frequency increment between the arrays and the transmit steering matrix carries angle,range even velocity information.Consider the range-angle coupling in transmit steering matrix,a subarray-based transmitted waveform and decoupling approach are designed.Utilizing the ESPRIT algorithm and ambiguity resolve methods based on FDA,the direction-of-departure(DOD),direction-of-arrival(DOA),range and velocity parameters are estimated unambiguously.Additionally,Cramér-Rao bounds(CRB)for these parameters are derived and the performance of this radar is analyzed.Simulation results indicates the validity of the proposed method.
