How does echo sounding work?

In: Technology [Edit categories]

Answer:

Echo sounding is the technique of using sound pulses directed from the surface or from a submarine vertically down to measure the distance to the bottom by means of sound waves.The distance is measured by multiplying half the time from the signal's outgoing pulse to its return by the speed of sound in the water which is more or less 1.5 km/s.(the speed of sound in water may slightly change by the factors of pressure, temperature and salinity).

The formula is:
D = 1/2*t*v
where:
D = distance
t = time in seconds
v = velocity in m/s

add. 'Doc' Edgerton, who had been a prime mover in the development of the Strobe Light, went on to make similar contributions to Side-scan Sonar.
