    The North American Industry Classification System or NAICS (/ n eɪ k s /) [1] is a classification of business establishments by type of economic activity (the process of production). It is used by governments and business in Canada , Mexico , and the United States of America .

  3. Pulse-Doppler radar - Wikipedia

    en.wikipedia.org/wiki/Pulse-Doppler_radar

    The Hughes AN/ASG-18 Fire Control System was a prototype airborne radar/combination system for the planned North American XF-108 Rapier interceptor aircraft for the United States Air Force, and later for the Lockheed YF-12. The US's first pulse-Doppler radar, [4] the system had look-down/shoot-down capability and could track one target at a time.

  4. Digital radio frequency memory - Wikipedia

    en.wikipedia.org/wiki/Digital_radio_frequency_memory

    Since a DRFM system is designed to create a false target to a radar system, this technology can be employed to perform hardware-in-the-loop simulation. [1] [2] Hardware-in-the-loop simulation is an aid to the development of new radar systems, which allows for testing and evaluation of the radar system earlier in the design cycle. This type of ...

  5. Radar jamming and deception - Wikipedia

    en.wikipedia.org/wiki/Radar_jamming_and_deception

    Concepts that blanket the radar with signals so its display cannot be read are normally known as jamming, while systems that produce confusing or contradictory signals are known as deception, but it is also common for all such systems to be referred to as jamming. There are two general classes of radar jamming, mechanical and electronic.

  6. Automatic target recognition - Wikipedia

    en.wikipedia.org/wiki/Automatic_target_recognition

    Automatic target recognition (ATR) is the ability for an algorithm or device to recognize targets or other objects based on data obtained from sensors.. Target recognition was initially done by using an audible representation of the received signal, where a trained operator who would decipher that sound to classify the target illuminated by the radar.

  7. Radar engineering - Wikipedia

    en.wikipedia.org/wiki/Radar_engineering

    Radar engineering is the design of technical aspects pertaining to the components of a radar and their ability to detect the return energy from moving scatterers — determining an object's position or obstruction in the environment.

  8. Height finder - Wikipedia

    en.wikipedia.org/wiki/Height_finder

    A height finder radar is a type of 2-dimensional radar that measures altitude of a target.. The operator slews the antenna toward a desired bearing, identifies a target echo at a desired range on the range height indicator display, then bisects the target with a cursor that is scaled to indicate the approximate altitude of the target. [7]

  9. AN/FPS-117 - Wikipedia

    en.wikipedia.org/wiki/AN/FPS-117

    The AN/FPS-117 is an L-band active electronically scanned array (AESA) 3-dimensional air search radar first produced by GE Aerospace in 1980 and now part of Lockheed Martin. [1] [2] The system offers instrumented detection at ranges on the order of 200 to 250 nautical miles (370 to 460 km; 230 to 290 mi) and has a wide variety of interference and clutter rejection systems.
