Arctic Dispersion Interruption Phenomenon and Sound Source Depth Estimation
Weng Jinbao, Yang Yanming, Chen Benqing +2
The sound speed profile in the deep Arctic Ocean causes the surface layer to form a normal mode waveguide. When the depth of the sound source or receiver is near a node of the eige…
Acoustic source depth estimation method based on a single hydrophone in Arctic underwater
Jinbao Weng, Yubo Qi, Yanming Yang +6
Based on the normal mode and ray theory, this article discusses the characteristics of surface sound source and reception at the surface layer, and explores depth estimation method…
Inversion of Arctic dual-channel sound speed profile based on random airgun signal
Jinbao Weng, Yubo Qi, Yanming Yang +6
For the unique dual-channel sound speed profiles of the Canadian Basin and the Chukchi Plateau in the Arctic, based on the propagation characteristics of refracted normal modes und…
Research and experimental verification on low-frequency long-range underwater sound propagation dispersion characteristics under dual-channel sound speed profiles in the Chukchi Plateau
Jinbao Weng, Yubo Qi, Yanming Yang +3
The dual-channel sound speed profiles of the Chukchi Plateau and the Canadian Basin have become current research hotspots due to their excellent low-frequency sound signal propagat…
Optimization of an underwater in-situ LaBr3:Ce spectrometer with energy self-calibration and efficiency calibration
Zhi Zeng, Xingyu Pan, Hao Ma +5
An underwater in situ gamma ray spectrometer based on LaBr3 was developed and optimized to monitor marine radioactivity. The intrinsic background mainly from La138 and Ac227 of LaB…
