Abstract

The invention discloses an in-situ measurement system and method for low-frequency acoustic characteristics in seabed sediments. The device comprises a bearing frame, a control cabin, a hydraulic cabin, a vertical feeler lever penetration mechanism and a horizontal feeler lever supporting mechanism are arranged in the bearing frame, a lifting ring is arranged at the top end of the bearing frame, and two receiving transducers which are vertically arranged at intervals are fixedly arranged at the bottom end of a vertical feeler lever; the horizontal feeler lever supporting mechanism comprises adriving device fixedly arranged on the bearing frame, the output shaft of the driving device is perpendicular to and fixedly connected with one end of the horizontal feeler lever, the driving device can drive the horizontal feeler lever to rotate with the output shaft as the center axis, and a transmitting transducer is arranged at the other end of the horizontal feeler lever. A control circuit isarranged in the control cabin, a penetration oil cylinder pressure sensor electrically connected with the control circuit is arranged in the hydraulic cabin, and the control circuit is electrically connected with the display control system through a cable. According to the invention, in-situ measurement of propagation characteristics of medium-low frequency sound waves in sediments is realized.

Description

technical field [0001] The invention relates to the technical field of seabed measurement equipment, in particular to an in-situ measurement system and method for low-frequency acoustic characteristics of seabed sediments. Background technique [0002] The seabed is an important boundary of the underwater sound field, and the acoustic characteristics of the seabed bottom have an important impact on the propagation of sound waves in seawater and the spatial structure of the underwater sound field. The measurement and research of the acoustic characteristics of the seabed have important application value in the fields of military, marine science and production, such as ocean acoustic field prediction, underwater target detection, underwater communication and navigation, seabed topographic mapping, and seabed resource exploration. The direct measurement methods of the acoustic properties of the seabed bottom mainly include laboratory measurement of sediment samples and in-situ ...
