Abstract:Underwater acoustic source localisation in deep water shadow zone is difficult since the vertical aperture of the array is limited and the received signal-noise ratio (SNR) is low. This article investigates a novel interference pattern in the first shadow zone. The intensity displays two oscillating striations in the interference pattern, which can be used to estimate the source depth under the restriction of lacking adequate spatial samples and acoustic environmental parameters, and the range of the source ca… Show more
