Abstract
1. Способ измерения скорости звука в воде, заключающийся в зондировании акустическим сигналом акустических рассеивателей, приеме рассеянных обратно от них акустических сигналов первым, вторым акустическими приемниками и установленным на одном горизонте с ними направленным акустическим излучателем-приемником, измерении времен прихода принятых сигналов, определении по их значениям, значению скорости звука на горизонте акустических источника и приемников, известным расстояниям между ними, а также углам прихода принятых сигналов скорости звука в воде на заданных горизонтах, отличающийся тем, что облучают импульсным акустическим сигналом одиночный относительно сильный естественный акустический рассеиватель, находящийся в водном объеме, ограниченном характеристиками направленности акустических излучателя-приемника, первого и второго акустического приемников, причем оси характеристик направленности приемников пересекаются на одном горизонте с осью характеристики направленности акустического излучателя-приемника, при этом последовательно изменяют углы наклона характеристик направленности первого и второго акустического приемников, а углы прихода принятых акустических сигналов определяют по их временам прихода до излучателя-приемника и обоих приемников.2. Способ по п.1, отличающийся тем, что излучают монохроматический импульсный акустический сигнал малой длительности.3. Способ по п.1, отличающийся тем, что излучают сложный импульсный акустический сигнал с внутренней гиперболической частотной модуляцией несущих колебаний, а времена прихода принятых сигналов определяют по временному положению 1. A method of measuring the speed of sound in water, which consists in sensing acoustic diffusers with an acoustic signal, receiving acoustic signals scattered back from them by the first, second acoustic receivers and placed on the same horizon as a directed acoustic emitter-receiver, measuring the arrival times of the received signals, determining their values, the value of the speed of sound on the horizon of the acoustic source and receivers, the known distances between them, as well as the angles of arrival of the received speed signals type of sound in water at predetermined horizons, characterized in that a single relatively strong natural acoustic diffuser is located in a water volume limited by the directivity characteristics of the acoustic emitter-receiver, the first and second acoustic receivers, and the axis of the directivity characteristics of the receivers intersect at one horizon with the axis of the directivity characteristics of the acoustic emitter-receiver, while tilting the x the directivity characteristics of the first and second acoustic receivers, and the angles of arrival of the received acoustic signals are determined by their arrival times to the transmitter-receiver and both receivers. 2. The method according to claim 1, characterized in that they emit a monochromatic pulse acoustic signal of short duration. The method according to claim 1, characterized in that they emit a complex pulsed acoustic signal with internal hyperbolic frequency modulation of the carrier oscillations, and the arrival times of the received signals are determined by the temporary position
