Problems solved by technology
[0003] Underwater communication detection equipment is limited by factors such as the special environment of the ocean acoustic field, the slow propagation speed of underwater acoustic signals, the narrow frequency band of communication signals, and the need for miniaturization of underwater equipment. The current underwater networking technology is only a single detection network or a single The communication network does not support the integration of underwater large-scale regional network communication detection

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 first target feature information from the detection data; and a subsurface buoy carrying a passive monitoring array, second communication detection integrated equipment and afirst CTD. The mobile node comprises a sub-buoy node carrying third communication detection integrated equipment and a UUV carrying fourth communication detection integrated equipment and a second CTD.
Description
technical field [0001] The invention relates to the technical field of underwater communication, in particular to an integrated system for underwater communication and detection. Background technique [0002] There are four working systems for the integration of communication and detection, which are time-sharing system, frequency-division system, beam-division system and all-sharing system. The time-sharing system divides the signal into communication signals and detection signals in time, the frequency division system divides the communication function and detection function of the signal in the frequency band, and the beam-division system uses different beams to realize the signal communication function and detection function. The full sharing system is communication The signal shares the same transmit waveform as the probe signal. Because radar has the characteristics of large aperture, high bandwidth, and rapid propagation, relatively mature integrated radar communicat...
