- W2385797600 abstract "In order to estimate the direction of arrival (DOA) of a broadband distributed source, a class of fast algorithms, such as central frequency algorithm, median algorithm and mean algorithm, are presented. The algorithms estimate the DOA of the broadband distributed source fron the secondary diagonal elements of the covariance matrices generated from every frequency domain of the received broadband signals, thus avoiding unwrapping of phases. Simulation results demonstrate that when SNR is high and spread angle is not big, the central frequency algorithm and the median algorithm are almost identical; while when SNR is low, the median algorithm outperforms the central frequency. Furthermore, the mean algorithm is not sensitive to the spread angle and has a better performance.;" @default.
