Embodiment 1
[0071] A submarine equipped with a communication device described in this example. Specifically, submarine A and submarine B are relatively stationary, and the steps of the communication link establishment process are:
[0072] S1. Submarine A first emits ultrasonic waves through the acoustic transponder installed on it, and the acoustic transducer on submarine B receives the ultrasonic waves emitted by submarine A, and realizes the positioning of submarine A through the long-range ultra-short baseline positioning system. Equipment A The distance x from device B is equal to 200;
[0073] S2. An adaptive connection mechanism is adopted. After 1s, submarine B locates A again, and the relative displacement △x and relative displacement angle △θ of submarine A to submarine B are obtained. Judging the relative position of submarine A and submarine B, submarine A and submarine B are relatively stationary, and perform a second handshake.

Embodiment 2
[0081] A submarine equipped with a communication device described in this example. Specifically, the maximum distance x allowed for communication 0 Equal to 500m, the maximum phase shift angle θ allowed during communication 0 equal to 45°.
[0082] S1. Submarine A first emits ultrasonic waves through the acoustic transponder installed on it. The acoustic transducer on submarine B receives the ultrasonic waves emitted by submarine A, and realizes the positioning of submarine A through the long-range ultra-short baseline positioning system. Submarine A The distance x from submarine B is equal to 200;
[0083] S2. An adaptive connection mechanism is adopted. After 1s, device B locates A again, and obtains that the relative displacement △x of submarine A relative to submarine B is equal to 100m, and the relative displacement angle △θ is equal to 30°. Determine the relative position of submarine A and submarine B. The relative displacement △x and relative displacement angle △θ...
