Sonar Echo refers to the phenomenon of sound waves bouncing off objects or surfaces and returning back to the source. It is a concept commonly used in the field of sonar technology, which stands for Sound Navigation and Ranging. Sonar is a technique that utilizes sound waves to navigate, detect, and locate objects under or above the water surface.
When a sonar system emits a sound wave, it travels through the medium, such as water or air. As the wave encounters an object in its path, a portion of it is reflected back towards the original source. This reflected wave, known as the sonar echo, contains valuable information about the object's distance, size, shape, and composition.
The sonar echo is detected by the sonar system through a receiver, which captures the returning waves. By measuring the time it takes for the echo to return, the distance between the sonar system and the object can be determined. Moreover, the amplitude and frequency content of the echo help in identifying the composition and characteristics of the object.
Sonar echo is widely used in various applications, including navigation, mapping underwater terrain, detecting submarines and schools of fish, and locating underwater structures like reefs and wrecks. It is an important tool for scientists, researchers, and naval personnel, providing crucial information for underwater exploration, defense, and resource management.
