A sonar image captured by Deep Sea Vision, an underwater scanning company, that may show the remains of Amelia Earhart’s lost Lockheed 10-E Electra aircraft in the Pacific Ocean (Deep Sea Vision)
"Sonar" can refer to one of two types of technology: passive sonar means listening for the sound made by vessels; active sonar means emitting pulses of sounds and listening for echoes. Sonar may be used as a means of acoustic location and of measurement of the echo characteristics of "targets" in the water. [ 4 ]
