- W3137630143 abstract "A traditional way of optical direction of arrival (DOA) estimation is to convert the DOA estimation problem into phase shift estimation. However, such an approach requires to digitize the relationship between the phase shifts and the optical powers before the DOA estimation. In this paper, an algorithm for more directly estimating the phase shift is proposed, which uses the ratio of two optical powers for more effective phase shift estimation. Simulation experiments are conducted, which show that the proposed algorithm can provide much better estimation accuracy than the traditional one-sensor based optical DOA estimation algorithm" @default.
