渤海海域海底地形多波束观测数据集（2018年）

该数据集为2018年对渤海的多波束水体影像调查原始数据，水体影像数据是多波束R2SONIC的原始数据，利用TCP/IP协议对声呐换能器发出的原始UDP包进行记录和解析，可根据R2SONIC的原始数据格式进行处理，声呐发射ping的频率为3-5个每秒，每满100M进行下一个文件记录，文件名为声呐发射时的机器时间

This dataset comprises raw multi-beam water column imaging survey data acquired in the Bohai Sea in 2018. The water column imaging data originates from the R2SONIC multi-beam sonar system. Original UDP packets transmitted by the sonar transducer are recorded and parsed via the TCP/IP protocol, and the data can be processed in accordance with the raw data format specifications of the R2SONIC system. The sonar ping emission frequency ranges from 3 to 5 pings per second. A new recording file is created once the current file reaches 100 MB in size, and the filename is the machine timestamp generated at the moment of sonar ping emission.
