Usikov Institute for Radiophysics and Electronics of the National Academy of Sciences of Ukraine popup.description2 The mechanisms and average energy and fluctuation characteristics of sound backscattering in natural gas flares on frequencies 3.2-120 kHz have been studied during 6 expeditions in Black sea organized by the NAS of Ukraine. Morphometric parameters of more than 800 flares, as well as target strength of single gas releases, volume backscattering strength flares, their probabilistic distribution and frequency dependencies have been determined. The methodology of determining bubble cloud dynamics in intensive gas flares has been developed. The methodology is based on the spatial-temporal correlation relationship of gas flares echo signals. Potentialities of correlation method have been studied by using numerical simulations and laboratory experiments. Mobile hydroacoustic software hardware for detection and diagnosis of gas releases from seabed has been developed. Product Description popup.authors Бережна Н.Д. Ківва Ф.В. Ломейко А.І.
