Abstract

Direction finding is an important issue for bistatic MIMO radar. A two-dimensional direction finding method with automatic pairing is developed. In the presented method, the property of the kronecker product is first utilized to reformulate the cost function in the quadratic form. Then, by constructing the orthogonality constraint of the target DOA to the quadratic form, all target DODs can be first estimated by solving the constrained quadratic form. Moreover, the pth target DOA can be directly estimated by the eigenvector which is related to the pth target DOD. Thus, the target DOD and DOA can be automatically paired. Finally, simulation results demonstrate that the effectiveness of the presented method.
