METHOD, MODULE AND SYSTEM FOR DETERMINING A VELOCITY PROFILE OF SOUND WAVES IN A WATER COLUMN

This method includes emitting, by an emitter at an emitting depth, moved along an axis, at least one incident sound wave at an emitting frequency, receiving a first sound wave reflected by a first reflective object at a first depth and a second sound wave reflected by a second reflective object at a...

Zusammenfassung:This method includes emitting, by an emitter at an emitting depth, moved along an axis, at least one incident sound wave at an emitting frequency, receiving a first sound wave reflected by a first reflective object at a first depth and a second sound wave reflected by a second reflective object at a second depth, greater than the first depth, providing a first velocity at the first depth, and determining a second velocity of the sound waves at the second depth, from the frequencies of the first and second reflected sound waves, the emitting frequency and the first velocity.
