Parent topics
- Radio [r]: Transmission and reception of information, which can be voice, data or imagery over electromagnetic radiation in free space (i.e., wireless). The information is modulated onto a carrier wave [e]
- Radar [r]: Acronym for "radio detection and ranging"; a system used to locate a distant object by transmission of radio waves and reception of their reflection. [e]
- Television [r]: Electronic transmission of moving pictures. [e]
Subtopics
- Oscillator [r]: Add brief definition or description
- Modulation [r]: The process of varying one waveform in relation to another waveform. [e]
- Amplitude modulation [r]: Changing the height of the peaks of a periodic waveform, such as a radio wave, to carry information. [e]
- Frequency modulation [r]: Technique for imposing information onto a electromagnetic signal of constant frequency -- the "carrier wave". [e]
- Superheterodyne [r]: A form of reception in which the frequency of an incoming signal is mixed with a locally generated signal and converted to an intermediate frequency in order to facilitate amplification and the rejection of unwanted signals. [e]
- Electronic warfare [r]: A subset of information operations that deals with the use of electromagnetic or kinetic means to degrade an enemy's military electronics systems, to be able to operate one's own electronics in the face of enemy attacks, and to evade those attacks through protection or deception [e]
- Digital selective calling [r]: A method to address specific marine radios or groups of vessels, and to send a distress signal, including the vessel's location if the radio is connected to a GPS receiver [e]
- Emergency Position Indicating Radio Beacon [r]: Intended for search and rescue of ships and boats, this is a beacon that will float free of a sinking vessel, and broadcast a position report, preferably with GPS, to a worldwide cluster of monitoring satellites. [e]
- Global Maritime Distress and Safety System [r]: Mandated by the Safety of Life at Sea convention of the International Maritime Organization system of digital radio and other systems for ships to receive alerts and signal search and rescue organizations when they are in distress. [e]
- HAVE QUICK II [r]: Add brief definition or description
- Information security [r]: The set of policies and protective measures used to ensure appropriate confidentiality, integrity and availability to information; usually assumed to be information in a computer or telecommunications network but the principles extend to people and the physical world [e]
- Led Zeppelin Radio [r]: A commercial-free, satellite radio station on the XM Satellite Radio platform, broadcasting the music of Led Zeppelin. [e]
- Marine navigation [r]: Add brief definition or description
- SIGINT in the Second World War [r]: Add brief definition or description
- SIGINT space-based platforms [r]: Add brief definition or description
- Safety and survivability of naval vessels [r]: Beyond the rules of the Safety of Life at Sea convention, protective measures, for naval vessels, against their own systems as well as enemy fire [e]
- Satellite communications [r]: Telecommunications that makes use of a high-altitude relay(s), usually artificial satellites in Earth orbits but potentially a relay in the atmosphere [e]
- Science fiction [r]: A story-telling genre that presents alternatives to what is currently considered scientifically possible or that extrapolates from present-day knowledge. [e]
- TRC-170 [r]: Add brief definition or description
- TRC-190 [r]: Add brief definition or description
- TSC-154 [r]: Add brief definition or description
