What Is a Sonar System?
A sonar system uses sound waves in order to detect, locate, and recognize any object or feature existing underwater. This underwater acoustic technology sends acoustic signals, analyzing their reflections in order to obtain information about the position and other properties of the target. Sonar devices are used in navigation, surveillance, underwater communication, and sea bottom exploration.
How Does Sonar Work?
Transmission of signal: Acoustic pulses are generated by the sonar device and are transmitted through the water medium through the transducer.
Propagation of sound: The acoustic wave travels through the water medium till it comes across any underwater object, seabed, or other objects.
Echo detection: The echo coming back is detected by the sonar device. The echo is captured by the transducer and converted into an electrical signal.
Processing of signal: The signal is processed by the sonar device in order to distinguish between the useful echoes and the surrounding noise and interference in acoustic form.
Detection of target: Detection of the target object and distance is done based on the processed data.
Displaying information: Information obtained is displayed through the display or software program for navigation and other purposes in underwater applications.
