Abstract

Abstract

A new algorithm to jointly estimate the DOD-DOA and Doppler frequency of bistatic MIMO radar is proposed based on the parallel factor. The receiver signal expression is derived under SweilingII target model, which shows it has three-way array model characteristics. Therefore, the uniqueness of the low-rank three-way array model decomposition is analysed. And the three parameters are jointly estimated from three matrices that are obtained from the low-rank decomposition. The new algorithm uses all of the received data and eliminates the error propagation of the several eigen decompositions because each iteration possesses a typical least square problem with a unique closed solution. Hence the estimation accuracy is increased. Furthermore, the estimated parameters are automatically paired without the additional pairing method, which the computational complexity of the proposed algorithm is reduced. Finally, simulation results are presented to verify the effectiveness of the proposed method.
