detection
1. In tactical operations, the perception of an object of possible military interest but unconfirmed by recognition. 2. In surveillance, the determination and transmission by a surveillance system that an event has occurred. 3. In arms control, the first step in the process of ascertaining the occurrence of a violation of an arms control agreement. 4. In nuclear, biological, and chemical (NBC) environments, the act of locating NBC hazards by use of NBC detectors or monitoring and/or survey teams. See also hazard; monitoring; nuclear, biological, and chemical environment. (JP 3-11)

detection
1. The recovery of information from an electrical or electromagnetic signal. (188 ) Note: Conventional radio waves are usually detected by heterodyning, i.e ., coherent reception/detection. In this method of reception/detection, the received signal is mixed, in some type of nonlinear device, with a signal from a local oscillator, to produce an intermediate frequency, i.e. , beat frequency, from which the modulating signal is recovered, i.e. , detected. The inherent instabilities of available optical sources have, until relatively recently, prevented practical use of coherent reception/detection in optical communication receivers. At present, coherent optical receivers, using sophisticated technology, are just beginning to emerge from the laboratory into the field. Virtually all existing optical receivers employ direct detection; that is, the received optical signal impinges directly onto a detector. Direct detection is less sensitive than coherent detection. [After FAA] 2. In tactical operations, the perception of an object of possible military interest but unconfirmed by recognition. [JP1] 3. In surveillance, the determination and transmission by a surveillance system that an event has occurred. [JP1]

Detection
In general, detection is the extraction of intelligence from a carrier signal in a communication system. Note that this may be either an overt signal, as in a conventional radio broadcast, or a covert signal, as in steganography.
In opto-electronic systems, the generation of an electrical signal in response to a received optical input. For example, the optical signal received from an optical fiber is converted to an electrical signal in a detector, often by a photodiode.
