Fast DOA estimation for monostatic MIMO radar with arbitrary array configurations

摘要：

A fast direction of arrival (DOA) estimation method is presented in this paper for monostatic multiple-input multiple-output (MIMO) radar with arbitrary array configuration. In order to avoid spectral peaks search in the multiple signal classification (MUSIC) algorithm and reduce the computational complexity, the proposed method uses manifold separation and polynomial rooting technique to estimate DOAs of the targets for the monostatic MIMO radar with arbitrary array configurations. The proposed polynomial rooting DOA estimation algorithm provides a lower computation complexity and a better resolution performance than the conventional MUSIC method. Finally, simulation results are presented to verify the effectiveness of the method.
