The military uses this technology as both a defensive and offensive tool. Today’s military applications of radar systems range from aircraft navigation and attack to air defence, weather detection, and air traffic control. Naval ships around the world use radar to identify surface targets and weather, too. Radar systems have been used in military applications for ground surveillance, missile control, fire control, air traffic control (ATC), moving target indication (MTI), weapons location, and vehicle search. Radar is a very important tool in the military as it is used to detect aircrafts, vehicles and missiles. Sonar is a very common technique used in submarines and other underwater vessels. It uses sound propagation to detect objects in the water. This is done by emitting sound pulses and listening for echoes. A radar system detects other aircraft, ships, or other objects and the speed and direction in which they travel by sending out a pulse of high-frequency electromagnetic waves. This pulse goes out ahead of the aircraft until it encounters an object and reflects off of it.
