Presentation title: Registration of hydroacoustic signals by coastal laser strainmeters
Abstract: The relevance of the work is to investigate the possibility of registering a source of hydroacoustic radiation by a system of spatially-spaced coastal laser strainmeters (LS), or a two-coordinate LS. The experimental complex includes onshore LS of stationary and mobile versions and low-frequency sonar emitting systems. The method of conducting experimental work is described, which makes it possible to investigate the possibility of receiving a signal at different distances from receiving systems and a moving signal source. According to the results of the experiment, it was confirmed that LS stably register signals from sources of hydroacoustic vibrations. The results obtained show the possibility of registering a source of hydroacoustic radiation as it moves through a controlled water area. In this case, the control can be carried out by combining two different measurement methods: 1) the method of spatially spaced LS; 2) the method of amplitude modulation of the signal of multidirectional components of LS. The results obtained showed the prospects of using a system of LS to register sources of low-frequency sonar radiation along the coast of offshore zones.
