With the development of satellite communication and remote sensing technologies, the long-distance real-time transmission of marine environment measurement data in the space above water has been realized.

Generally, a marine instrument is used for multi-parameter measurement, a plurality of underwater sensors are arranged in water layers with different depths, and obtained measurement data are transmitted to a water terminal device through a multi-core cable. The adopted multi-core cable is an armored cable, which not only has enough tension to tie a plurality of underwater sensors, but also can respectively transmit the measurement data of each underwater sensor.

However, the above-mentioned marine survey mostly uses a cable for data transmission, and has high cost and low matching flexibility, and further requires an expensive, power-consuming, and failure-prone acoustic modem.
