Description
Technical field [0001] The invention relates to a technology in the field of underwater acoustic equipment, in particular to an underwater acoustic buoy monitoring system triggered by multi-mode signal acquisition. Background technique [0002] With the deepening of ocean development, the related technology of underwater detection is getting more and more attention. Distributed underwater acoustic monitoring buoys play a pivotal role in marine environmental noise monitoring, active / passive acoustic performance evaluation of underwater targets, and stereo protection of sea battlefields. However, the existing underwater acoustic buoy monitoring system has a single working mode and high power consumption, which is difficult to meet the requirements of a complex working environment. At the same time, the existing device is large in size, high in cost, low in efficiency, and not conducive to large-scale applications. Summary of the invention [0003] Aiming at the above-mentioned shor...
