● Acquiring the sub-bottom structure of the near-shore-ocean floor
● Detecting the conditions of shallow buried targets on the near-shore ocean seabed
● Wet end:transducer,20 meter cable.
● Dry end:including transmitter,receiver,power supply and processing controller.
The HY-MPSB 100 is a parametric array sub-bottom profiler, developed by our company in collaboration with the East China Sea Station of the Institute of Acoustics, Chinese Academy of Sciences. This module collects the shallow seismic geotechnical data of the water bottom by emitting high-frequency acoustic signals with a range of 85kHz to 115kHz and receiving the response of the medium. Based on the principle of phased parametric arrays, this device features a small transducer size, high resolution, high sensitivity and rapid imaging. It is crucial for the exploration of underwater subsurface structures and the detection of target embedding
