Abstract

In Non-Coherent Direction Of Arrival (DOA) estimation, the goal is to determine DOA based only on the magnitude of the received sensor array signal. The advantage of the Non-Coherent DOA estimation is its robustness against phase errors; despite phase errors present in both sensors and phase shifters, direction of arrival can be estimated. In this paper, DOA is estimated using a Frequency Estimation technique which can be simply implemented by discrete Fast Fourier Transform (FFT) methods. In addition, for removing the ambiguity and solving the nonlinear equations, a reference target with high power emission is used. Simulation results, in both linear and plane array cases show the efficiency and robustness of the proposed algorithm against phase errors.
