Used high-tech equipments including Sonar system in the operation

Teams from 6 NDRF Vadodara used high-tech equipments to search for the two persons drowned inside Narmada canal in Ahmedabad. The teams used water rescue equipments, high speed inflatable boats, Sonar system and other water communication systems in the operation.

On Thursday the drowning incident in Narmada Canal at Ahmedabad. The incident  happened Thursday afternoon at around 50 meter downstream of a barrage in the Narmada Canal in which Preet Bharat Adroja

S/O BHARAT Adroja and Dharmit Dhirubhai kasundra S/O Dhirubhai kasundra from Disrict Morbi, Gujarat aged  approx around 21 years drowned.

As per R.K. Mishra 6 Bn NDRF PRO Vadodara

“Despite very High speed of  stream, whirling water and darkness NDRF team full of deep drivers and Water rescue equipments High speed inflatable boats, Sonar system and other water  communication systems started the operation under supervision and continuous monitoring of Commandant 6 Bn  R. S.Joon. Due to his expertise in such type of difficult situation team successfully put down NDRF boats in very high speed of stream  and whirling water NDRF Started the search  operation”.

Sonar (originally an acronym for Sound Navigation Ranging) is a technique that uses sound propagation (usually underwater, as in submarine navigation) to navigate, communicate with or detect objects on or under the surface of the water, such as other vessels. Two types of technology share the name “sonar”: passive sonar is essentially listening for the sound made by vessels; active sonar is emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of “targets” in the water.

Acoustic location in air was used before the introduction of radar. Sonar may also be used in air for robot navigation, and SODAR (an upward looking in-air sonar) is used for atmospheric investigations. The term sonar is also used for the equipment used to generate and receive the sound. The acoustic frequencies used in sonar systems vary from very low (infrasonic) to extremely high (ultrasonic). The study of underwater sound is known as underwater acoustics or hydroacoustics.

Two more teams of NDRF rushed to place to engage in search operation. Earlier the team also went to Nadurbar to engage is search and rescue operation at Nadurbar after a boat capsized there.
