Abstract

Abstract:

Aiming at the angle estimation for coherent sources in bistatic MIMO radar, two methods based on the dimension reduction DOA matrix are presented in spatially white noise and in spatially colored noise, respectively. Firstly, the virtual array data of multi-target echoes in MIMO receivers is uncorrelated. Secondly, DOA matrices in different noise environments are constructed. The dimension reduction DOA matrices which reduce the computational complex are obtained by the relationship between signal subspace and DOA matrices. Finally, the joint estimation of DOD and DOA can be obtained by the corresponding relationships between the eigenvalue or eigenvector and the estimated parameters. The proposed methods do not need the multi-dimensional peak search, and can estimate the parameters of coherent sources without pairing in both two noise circumstances. Moreover, it is applicable to receiving arrays without an invariance structure. Numerical results are presented to demonstrate the effectiveness of the method advanced.

Key words: bistatic, MIMO radar, coherent source, spatially Gaussian white noise, spatially gaussian colored noise
