  Abstract

In the paper, we propose a new direction detection scheme of the ship whistle for the digital sound reception system (SRS) of ships based on the frequency detection and the phase difference estimation using correlation values between the received signals for two neighboring microphones under a white Gaussian noise environment. In order to suppress the noise, the proposed correlation-based frequency detector and phase difference estimator accumulate the correlation values for all possible combinations of two neighboring microphones. By utilizing the estimates of the phase differences for all combinations of two neighboring microphones, the proposed direction detection algorithm distinguishes the sector for the direction of the whistle signal and estimates the arrival angle. In addition, using the practically implemented SRS hardware and software, the laboratory test for the proposed schemes is performed and test results are presented.
