Abstract

The invention discloses an underwater communication system based on a very-low-frequency magnetoelectric antenna and a manufacturing method. The system comprises a signal transmitting end upper computer, a signal transmitting end lower computer, a power amplifier, a very-low-frequency magnetoelectric transmitting antenna, a signal receiving end upper computer, a signal receiving end lower computer and a very-low-frequency magnetoelectric receiving antenna. The very-low-frequency magnetoelectric transmitting antenna and very-low-frequency receiving antenna structure comprises a piezoelectric material, an electrode plate, a flexible electrode, a magnetostrictive material, an adhesive, a binding post, a PCB, a permanent magnet material, an SMA interface and a waterproof shell. According to the underwater communication system based on the very-low-frequency magnetoelectric antenna, underwater signal receiving and transmitting based on the magnetoelectric antenna are achieved for the first time, and compared with other underwater communication systems, the underwater communication system based on the very-low-frequency magnetoelectric antenna has the advantages of being small in size, low in price, free of alignment and high in environmental adaptability.

Description

technical field [0001] The invention belongs to the field of underwater communication systems, in particular to an underwater communication system based on a very low frequency magnetoelectric antenna and a manufacturing method. Background technique [0002] Underwater wireless communication is widely used in civil and military fields, including long-range communication between base stations and submarines, short-range communication between divers, and autonomous underwater vehicles (AUV), remotely operated vehicles (ROV) and underwater Under the control of wireless sensor network (UWSN). The growing demand for real-time acquisition and exchange of marine information has put forward higher requirements for underwater wireless communication technology. In shallow water and crowded water environment, underwater acoustic communication usually has problems such as large environmental noise, high time delay, strong reflection and attenuation caused by multipath propagation, and ...
