摘 要：The use of sonar by humans was first recorded by Leonardo da Vinci in 1490. Intense research on the concept of sonar technology as it is known today was prompted by the Titanic disaster of April 1912. During the World War I the need to detect submarines fueled more research for sonar development. Active sonar is used for civilian purposes like oil exploration activities, fishing, and hydrographic and nautical charting activities. Passive sonar is used in military activities. Active sonar generates a pulse of sound and listens for its reflections when the pulse hits an object. Passive sonar, on the other hand, listens without transmitting.
