A sonar is a device that through ultrasound can find the position of different objects, it is mainly used to search for different things in the sea, such as shipwrecks or schools of fish. There are two types of sonar, one passive, which works only as a receiver and picks up the waves emitted by underwater objects, and an active one, whose operation is mainly through a transducer, which functions as a signal emitter, mounted, by example, in the hull of a ship. This transducer emits the signal in a rectilinear path until it collides with an object, when the wave is reflected it is received by another transducer, which is responsible for converting it to an image to be seen through a monitor (Balone, 2014; Arribas, 2011).
