Direction of arrival estimation using nonlinear function of sum and difference beam
In this paper, a high resolution direction of arrival (DOA) estimation algorithm is proposed that based on the usage of nonlinear function of sum and difference beam. The generalized expression of this technique for different scenarios was derived in details. Unlike the conventional high resolution algorithm such as the MVDR, the MUSIC, and the ESPRIT, the proposed algorithm keeps the high resolution ability under low Signal-to-Noise Ratio (SNR) conditions. In addition, the proposed algorithm is suitable for real-time applications in that it has low computation complexity. Simulation results verified the validity of the proposed algorithm.
