Problems solved by technology
[0003]At present, most of the underwater preset equipment is powered by batteries. Once the battery is exhausted, it will sink and self-destruct immediately, which restricts its long-term underwater working ability; underwater work The UUV needs to be regularly recycled to the mother ship for charging and exporting data, which is very inconvenient and difficult to meet the needs of actual use

Description
technical field [0001] The invention relates to the technical field of design and manufacture of underwater acoustic equipment, in particular to an underwater energy and signal transmission system based on adaptive feedforward signal anti-jamming. Background technique [0002] Due to the huge attenuation of electromagnetic signals underwater, underwater signal transmission is currently blank. The reason why the transmission of some electromagnetic waves in the air is limited is mainly due to the absorption frequency bands of water vapor, oxygen, and carbon dioxide in the air. Water is a special medium, and its molecular structure is a polarized binary structure. Under the action of high-frequency electromagnetic waves, it will quickly convert electromagnetic energy into mechanical energy, causing the water temperature to rise rapidly, while consuming and absorbing electromagnetic energy, thus greatly inhibiting the propagation of electromagnetic signals in water. Efficient ...
