[3] sonar (short for sound navigation and ranging) A system for the detection of objects and for measuring the depth of water. It works by emitting sound pulses and measuring how long it takes the echoes to return. 36 questions with answers in SONAR | Science topic - ResearchGate JMSE | Free Full-Text | Sample Augmentation Method for Side-Scan Sonar ... Here, a sonar image formed by imaging the flat ground at the same fixed tilt angel and altitude is selected as the reference image. It is assumed that the reductions of reflection intensity are similar at the same distance. ...

The Development of RADAR and SONAR | Encyclopedia.com Nature's sonar: Scientists reveal how Japanese horseshoe bats perceive moving objects. by Doshisha University. Graphical abstract. Credit: iScience (2024). DOI: 10.1016/j.isci.2024.109222.... Sonar is an acoustic wave (whose uses are roughly analogous to radar) and whose name is an acronym for "sound navigation and ranging." Sonar consists of pulses of sound waves are transmitted into water, usually at ultrasonic frequencies in the range of 20-100 kHz. They travel out and are reflected by a solid object. By Damond Benningfield. Although it's best known from Hollywood movies, with tense submarine crews listening to the "pings" from enemy ships, sonar is an important tool for exploring the oceans. Over the last few decades, marine scientists have used it to map the ocean floor. Sonar, which is short for "Sound Navigation and Ranging" is used to help both explore and map the ocean. It is especially useful in ocean exploration because sound waves have the ability to travel more efficiently through the water (and farther) as opposed to light or radar waves, which have also been used in the past to help explore the ocean. Sonar: Meaning, Technique, Applications - Collegedunia SONAR, short for SOund NAvigation and Ranging, is a tool that uses sound waves to explore the ocean. Scientists primarily use sonar to develop nautical charts, locate underwater hazards to navigation, search for and identify objects in the water column and on the seafloor such as shipwrecks, and map the seafloor itself. The scarcity and difficulty in acquiring Side-scan sonar target images limit the application of deep learning algorithms in Side-scan sonar target detection. At present, there are few amplification methods for Side-scan sonar images, and the amplification image quality is not ideal, which is not suitable for the characteristics of Side-scan sonar images.
