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]: Add brief definition or description
- Signals intelligence [r]: Add brief definition or description
- Radiofrequency MASINT [r]: Add brief definition or description
- 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 before the Second World War [r]: Add brief definition or description
- SIGINT from 1945 to 1989 [r]: Add brief definition or description
- SIGINT ground-based platforms [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]: Add brief definition or description
- Satellite communications [r]: Add brief definition or description
- Science fiction [r]: Add brief definition or description
- TRC-170 [r]: Add brief definition or description
- TRC-190 [r]: Add brief definition or description
