Sonar , technique for detecting and determining the distance and direction of underwater objects by acoustic means. Sound waves emitted by or reflected from the object are detected by sonar apparatus and analyzed for the information they contain. Learn more about sonar in this article. Sonar (Sound Operated Navigation And Ranging) uses sound propagation to detect, navigate or communicate under the surface of water. This post will discuss in detail the meaning of Sonar , it’s types, architecture, how it works, applications , advantages and disadvantages. Sonar (Sound Navigation And Ranging) is a technology used to identify and locate objects underwater. It is also used to measure water depth (bathymetry). Sonar is used underwater because sound waves taper off less as they travel through water than light or sound waves. Before the invention of sonar , crews would use lead lines to systematically take soundings of the ocean floor. This allowed them to create early bathymetric maps and depth charts. The first practical use of sonar was during ... SonarQube provides automated code quality and security reviews, delivering actionable intelligence that helps developers build better and faster.
