A hydrophone is an underwater listening device, just as a microphone is used to detect sound in the air. Hydrophone detects sounds in the water and converts the acoustic energy into electrical energy by detecting changes in pressure in the surrounding environment. Hydrophones listen to sounds in the sea, but …

Aircrafts & Drones are becoming increasingly important for Anti-Submarine Warfare (ASW) missions
Three decades ago, only a handful of major powers had effective submarine capabilities but, today, fleets in operation around the world are growing rapidly. Emerging superpowers, like China, can add naval capacity equivalent to a European country’s in the space of a few years. The threat from submarines is serious …

Sonar (sound navigation and ranging) is a technology that uses acoustical waves to sense the location of objects in the ocean. SOund Navigation And Ranging or SONAR is a technique of distance measuring between detector and an object base on sound reflection. The distance can be calculated from propagation time and …

Submarines carry out extremely important and diverse roles including intelligence gathering, surveillance, reconnaissance, insertion and extraction of divers or special forces, attacking enemy submarines and their surface warships, mine laying, together with other littoral or choke point operations. Naval Warfare depends a large extent on lethality and survivability of submarines, …

The Arctic region encompasses the seas and land north of latitude 66.33° N. The Arctic Ocean is the smallest of the world’s oceans but is transforming due to its melting ice. Eight countries possess territories there: Canada, Denmark (through possession of Greenland), Finland, Iceland, Norway, Russia, Sweden and the US. …

Underwater communication is vital for undersea exploitation and modern communication. Conventional ways which employ acoustical technique for underwater communication have their drawbacks including high path loss, narrow bandwidth, high bit error rate, among which unconditional security is more demanding due to commercial and secure interest. Submarine communications have always been a challenge …

Alexander Graham Bell discovered photoacoustics by accident when he was working on the development of the photophone, a followup to his recently developed telephone that operated via modulated sunlight instead of electricity. You would operate a photophone by speaking into its transmitter toward a mirror placed inside of it. The vibrations …
