Correction of velocity estimation bias caused by phase-shift beamforming in acoustic Doppler velocity logs
收藏 引用
IET RADAR SONAR AND NAVIGATION 2024年 第7期18卷 1116-1131页
作者: Jia, Kuankuan Xu, Weijie Ma, Li Chinese Acad Sci Shanghai Acoust Lab Shanghai Peoples R China Chinese Acad Sci Inst Acoust Beijing Peoples R China Chinese Acad Sci Key Lab Underwater Acoust Environm Beijing Peoples R China Univ Chinese Acad Sci Beijing Peoples R China
The performance of Doppler velocity logs (DVLs) in terms of velocity estimate error is directly linked to the geometry of the beam and the pulse transmitted. Beyond a specific transmitted bandwidth, the phase-shift be... 详细信息
