Abstract

Abstract

In order to solve the problem of Direction Of Departure (DOD), Direction Of Arrival (DOA) and Doppler frequency estimation in bistatic MIMO radar, a low complexity method is proposed for joint estimation of the three parameters based on the multi-dimensional Vandermonde structure characteristic of the parameter manifold matrices. First, a third-order tensor is constructed according to the multi- dimensional structure of the echo model. Three equivalent matrices are obtained by cutting the tensor along transmit dimension, receive dimension and pulse dimension respectively. Then, combining the multi-dimensional Vandermonde characteristic with the Khatri-Rao product characteristic of the left-singular matrix of the equivalent matrix, transmit manifold matrix, receive manifold matrix and Doppler manifold matrix are estimated. Finally, the DOD, DOA and Doppler frequency are estimated by Root-MUSIC algorithm. Compared with the existence methods, the proposed algorithm improves obviously the estimation precision, and its computational cost is comparable to that of Estimation of Signal Parameters via Rotation Invariant Techniques (ESPRIT) method in small pulse number. The effectiveness of the proposed method is verified by simulation results.
