Far above the ocean’s surface, aircraft hunt for an unseen enemy below the waves is extremely complex and difficult. Finding enemy submarines in a real-world situation is like “finding a needle in a haystack.” Anti-submarine missions can involve a lot of figuring out where an enemy is not and then closing in on the target, like playing the classic board game of Battleship, except, in this case, your opponent can see both sides of the board.
Acoustic sensors look for sound pressure waves under the water, while electromagnetic sensors identify various parts of the electromagnetic spectrum. As for active sensors, they emit a shaped pulse of energy, or a ping, and collect any returning signal that has reflected off part of the submarine. Passive sensors, meanwhile “listen” to and collect any noise in the environment, which hopefully includes an emission from the target.
Let’s check the details of these sensors used by aircraft to detect submarines.
