Working of SONAR

SONAR has two components

  1. A transmitter- for transmitting ultrasonic waves
  2. A detector- for detecting the reflected ultrasonic waves

Sonar is installed in a boat or a ship.

  • The transmitter transmits ultrasonic waves.
  • These waves travel through water and after striking the object on the seabed, get reflected back and are sensed by the detector.
  • The detector converts the ultrasonic waves into electrical signals, which are later interpreted.
