A laser designator is a laser light source which is used to designate a target. Laser designators provide targeting for laser-guided bombs, missiles, or precision artillery munitions, such as the Paveway series of bombs, AGM-114 Hellfire, or the M712 Copperhead round, respectively. When a target is marked by a designator, the beam is invisible ...
Radar beacon. Racon signal as seen on a radar screen. This beacon receives using sidelobe suppression and transmits the letter "Q" in Morse code near Boston Harbor (Nahant) 17 January 1985. Radar beacon (short: racon) is – according to article 1.103 of the International Telecommunication Union's (ITU) ITU Radio Regulations (RR) [1 ...
RTX Corporation, formerly Raytheon Technologies Corporation, is an American multinational aerospace and defense conglomerate headquartered in Arlington, Virginia.It is one of the largest aerospace and defense manufacturers in the world by revenue and market capitalization, as well as one of the largest providers of intelligence services.
The Current Procedural Terminology ( CPT) code set is a procedural code set developed by the American Medical Association (AMA). It is maintained by the CPT Editorial Panel. [1] The CPT code set describes medical, surgical, and diagnostic services and is designed to communicate uniform information about medical services and procedures among ...
Chord (peer-to-peer) In computing, Chord is a protocol and algorithm for a peer-to-peer distributed hash table. A distributed hash table stores key-value pairs by assigning keys to different computers (known as "nodes"); a node will store the values for all the keys for which it is responsible. Chord specifies how keys are assigned to nodes ...
The National Codification Bureaus or NATO Codification Bureaux (NCB) are a NATO organization that oversees the management of the NATO Codification System (NCS). It is governed by NATO Allied Committee 135 (AC/135), with each member nation's National Codification Bureau controlling and issuing its own unique NATO Stock Numberss. [1]
Look-down/shoot-down radars have been enhanced with electronic programs that process the radar image and search for moving objects, which are detected by looking for Doppler shifts in the radar return. See moving target indication. The radar removes all stationary objects (e.g. the ground and buildings) from the display and shows only moving ...
An ARRL Numbered Radiogram is a brevity code used in composing ARRL Radiograms during times of radio congestion. The code is used to transmit standard messages, sometimes with customized text, very quickly by experienced ARRL National Traffic System (NTS) message traffic handlers.
A radioactive tracer can also be used to track the distribution of a substance within a natural system such as a cell or tissue, [1] or as a flow tracer to track fluid flow. Radioactive tracers are also used to determine the location of fractures created by hydraulic fracturing in natural gas production. [2] Radioactive tracers form the basis ...
In 3D computer graphics, ray tracing is a technique for modeling light transport for use in a wide variety of rendering algorithms for generating digital images . On a spectrum of computational cost and visual fidelity, ray tracing-based rendering techniques, such as ray casting, recursive ray tracing, distribution ray tracing, photon mapping ...
