Uses of SONAR Sonar technology is primarily used to calculate the depth, range, and direction of presence of objects. Below are some uses of sonar technology: For underwater communications, ships and submarines use special sonars. Sonar is used in medical imaging to detect cysts and cancer cells, and this process is known as sonogram. 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 | SonarScanner : a step by step guide. #StaticAnalysis.
