Принцип действия гидроакустического

Принцип действия гидроакустического корреляционного лага (ГКЛ) заключается в измерении временного сдвига между идентичными акустическими сигналами, принятыми двумя судовыми антеннами, разнесенными на определенное расстояние, получившими с движущегося судна отраженный от грунта сигнал. На глубинах до 200 м. ГКЛ измеряет скорость относительно грунта и одновременно указывает глубину под килём. На больших глубинах он автоматически переходит на работу относительно воды. Достоинствами ГКЛ по отношению к ГДЛ являются независимость показаний от скорости распространения звука в воде и более надёжная работа на качке.

The principle of operation of the hydroacoustic log correlation (GP) is the measurement of the time shift between identical acoustic signals, adopted two shipboard antennas for a certain distance apart, obtained from a moving ship signal reflected from the ground. At depths up to 200 m GP provides speed over ground and simultaneously indicates the depth under kilëm. At great depths it automatically goes to work relative to the water. Advantages of GP relative to the GDL are independence of the reading from the speed of sound in water and more reliable work on rocking motion.

The principle of operation of the hydroacoustic correlation lag (FCL) consists of measuring the time shift between identical acoustic signals received by two ship's antennas spaced a certain distance, is received from a moving ship signal reflected from the ground. At depths of 200 m. GCR measures the speed over the ground at the same time indicates the depth under the keel. At greater depths, it automatically goes to work through the water. GCR advantages with respect to the independence of the GDL are indications of the speed of sound in water and more reliable work on pitching.

the principle of the correlation of hydroacoustic (гкл) is the measurement of the time shift between identical acoustic signals by the two ship's antennae.разнесенными at a certain distance from a moving vessel, which is reflected from the ground signal. at depths up to 200 m. гкл measures the velocity on the ground and at the same time indicates the depth under the килём.at greater depths, it automatically goes to work on the water.advantages гкл to dgf are independent evidence of the speed of sound in water and a more secure job at the swaying.
