1. An acoustic wave-based full-sea-depth-covering undersea wireless charging method, comprising:
charging unmanned undersea vehicles UUV within 10 meters below the water-level from a mother ship, wherein a transmitting transducer is mounted on the mothership, a hydrophone is installed on the UUV;
charging the unmanned undersea vehicles UUV within 10-100 meters below the water-level via a sound wave directly sent to an underwater sensor node from the mother ship, wherein the transmitting transducer is installed on the mother ship, the hydrophone is mounted on the underwater sensor node;
charging the underwater sensor node at close range by unmanned undersea vehicles UUV in situ charge at the depth of more than 100 meters below the water-level, wherein the transmitting transducer is installed on the UUV, the hydrophone is mounted on the underwater sensor node.
