The transmitter in SONAR produces and transmits powerful ultrasonic waves. The ultrasonic waves travel through the water and after striking the target the beam is reflected from the seabed and is received by an under-water detector (mounted on the ship). The detector then converts the waves into electrical signals which are properly interpreted

Passive SONAR consists of only a receiver. The receiver receives ultrasonic waves produced by objects like engines of ships and submarines. This technique is used in national security and defense sectors to detect the presence of enemy ships or submarines in the oceans. Sonication is a process in which ultrasonic waves are used to agitate. Medical applications. Although ultrasound competes with other forms of medical imaging, such as X-ray techniques and magnetic resonance imaging, it has certain desirable features—for example, Doppler motion study—that the other techniques cannot provide.In addition, among the various modern techniques for the imaging of internal organs, ultrasonic devices are by far the least expensive Ultrasonic or Supersonic is the study of pressure waves which are of the same nature of the sound waves of very high frequency above the range of human audibility. Human hearing range is 16 to 20,000 Hz (Hertz). But ultrasound range is 21 to 101, 000 Hz. Ultrasound can be produced by using restrictive and pies electric, methods Intense ultrasonic radiation has disraptive effect on liquids by causing bubbles to be formed. Applications of Ultrasonic Waves. Ultrasonic waves are used for the following purposes. Ultrasonic flaw detection. Cutting and matching of hard materials. Ultrasonic soldering and welding. Measurement of flow devices. Applications in medicine. Thermal. • SONAR technology is similar to radar, ultrasound and seismics technologies. • There are two main types of SONAR viz. passive sonar and active sonar as shown in the figure-1. Passive SONAR relies on acoustic noise waves radiated by under water targets for its operation. • Active Sonar transmits acoustic signal which propagates towards.

Sonar stands for Sound Navigation Ranging. Sonar is used in navigation, forecasting weather, and for tracking aircraft, ships, submarines, and missiles. Sonar devices work by bouncing sound waves off objects to determine their location.

Topic: UltrasoundWhy is ultrasound used in sonar?Hey. Looks like you are searching for a treasure hidden in a sunken ship.Why don't you use a sonar?It will e.. Humans can normally hear sound frequencies between 20 and 20,000 Hz (20kHz). When a sound wave's frequency lies above 20 kHz, it is called an ultrasonic wave. While we cannot hear ultrasonic waves, we apply them in various technologies such as sonar systems, sonograms, surgical tools, and cleaning sytems Ultrasonic sensors are used around the world, indoors and outdoors in the harshest conditions, for a variety of applications. Our ultrasonic sensors , made with piezoelectric crystals, use high frequency sound waves to resonate a desired frequency and convert electric energy into acoustic energy, and vice versa Ultrasound. Ultrasound is sound with a frequency higher than 20 kHz. This is above the human range of hearing. The most common use of ultrasound, creating images, has industrial and medical applications. The use of ultrasound to create images is based on the reflection and transmission of a wave at a boundary These waves goes through the water and after striking the object and is received by under water detecter. The detecter converts the ultrasonic waves into electrical signal. The time interval between transmission and ultrasonic signal is note down. SONAR method is also called echo ranging. Application Of SONAR: It is Use for estimation of range

SONAR is a technique that uses sound waves to map or locate objects in the surrounding environment. The premise is quite simple: first, emit a cluster of sound waves in the direction of an object. While a few waves will bounce off it, the remaining waves will be reflected back in the direction of the emitte Ultrasonic Non destructive Testing - Industrial Applications of Ultrasonic waves Principle: The basic principle behind the ultrasonic inspection is the transmission of the Ultrasound with the medium and the reflection or scattering at any surface or internal discontinuity in the medium due to the change in the acoustic impedance
