Question

explain the principle, construction and working of SONAR?

Answer 1

The acronym SONAR stands for Sound Navigation and Ranging. Sonar is a device that uses ultrasonic waves to measure the distance, direction and speed of underwater objects. ...

Both radar and sonar locate objects from the echo of a signal that is bounced off the object. Radar uses radio waves, which are a type of electromagnetic energy. Sonar uses the echo principle by sending out sound waves underwater or through the human body to locate objects. Sound waves are a type of acoustic energy.

Sonar uses the echo principle by sending out sound waves underwater or through the human body to locate objects. Sound waves are a type of acoustic energy. Because of the different type of energy used in radar and sonar, each has its own applications.

Answer 2

Principle, construction and working of SONAR:

The SONAR means the Sound Navigation Ranging.

Principle of SONAR:

• When the ultrasonic waves are transmitted via water. It has been reflected by the object which is in water and an echo signal will produce.
• By the signal, we will find the object's distance easily.

Construction of SONAR:

• It is sound Propagation to navigate, communicate and detect the object.  
• SONAR uses the wave frequency higher than human detection capacity. These frequency can locate the object in the deep water of sea or ocean.

Application of SONAR:

• Certainly SONAR is use for various detection of old antique object under sea or detection of certain plane crash particle under the sea.  

• Military Vesseles carry sonar systems that is used for the detecting and tracking of enemy Vesseles.
