Sound navigation and ranging or Sonar is used for exploring, detecting, and mapping the ocean, since, sound waves travel farther in the water and experience less attenuation than radio frequency and optical signals. Sonar systems record the sound waves using hydrophones and process the signals to detect, locate, and classify different objects. The sonar system can be classified into two types - active and passive. Active sonar systems emit acoustic signals into the water and if an object is in the path of the sound pulse, the reflected signal returns an “echo” to the sonar transducer. Based on the time between the emission and reception of the acoustic pulse, the range and orientation of the object can be determined. Passive sonar systems are used to detect noise from marine objects without emitting its signal. This system is highly advantageous for military vessels that do not want to reveal its location to enemy military vessels in the water. Multiple passive sonar devices are used for the triangulation of a sound source. Sonar systems are widely being used for hydrography, oil exploration, fishing, and nautical charting activities.
