Underwater communication and detection integrated system

The invention provides an underwater communication and detection integrated system, and is used for realizing detection and communication integration for an underwater application scene, guaranteeingthe normal communication performance of the system, considering the active detection capability of the system, effectively utilizing a channel and improving the signal utilization rate. The system comprises a fixed node and a mobile node. The fixed node comprises a main buoy node which carries first communication detection integrated equipment and is used for detecting an underwater target to obtain detection data and performing underwater data communication; e wireless communication equipment which is used for broadcasting the first target feature information or sending the first target feature information to a shore-based data center and can also receive a control instruction and communication information; signal processing equipment which is used for extracting the target frequency spectrum information and the
