SONAR stands for Sound Navigation And Ranging.

It is used to find depth of the sea bed or to find underwater objects like fish colonies, submarines and ancient shipwrecks.

SONAR uses the technique of ultrasonic waves to find depth distance, direction and also speed of the object located underwater.

A SONAR consists of 2 parts :
1) a transmitter that emits ultrasonic waves.
2) a detector that receives the reflected ultrasonic waves.

The transmitter emits ultrasonic waves that travel to the depths of sea to the bottom. The ultrasonic waves strike the bed of the sea or any underwater object, it gets reflected back (echo) and is detected by detector  .

The detector's job is to convert the reflected ultrasonic waves into electrical signals that are interpreted.

If we know the speed of water and time taken between transmission and reception of wave, then the distance of the underwater object can be calculated.

There is a formula.

2d = v x t

here, 2d = total distance traveled by ultrasonic wave
v = speed of sound in water
t = time taken

Hope This Helps You!

SONAR-------------- Sound Navigation And Ranging
------------------------------
it is used to find the depth of the oceans , sea beds . shipwrecks , large objects ,lost submarines , airplanes which have sinked in water etc  
------------------------------
SONAR follows the principle of echo , a ultrasound will be sent through water and the time taken for the sound to reflect and come back will be calculated and after that distance will be measured
----------------------------------------------------
A SONAR consists of 2 parts :1) transmitter which will emit ultrasonic waves2) detector which receives the reflected ultrasonic waves
---------------------------
the transmitter will emit the ultrasonic sound and after the sound gets reflected back it will be detected by the detector and converts it into electrical signals 
------------------------------------------
time taken , speed , etc will be taken into consideration , distance will be calculated

the formula is 2d = v x t

2d -- distance traveled by sound
v --speed of sound in water 
t = time
