  • Radar cross section — (RCS) is a measure of how detectable an object is with a radar. For example a stealth aircraft (which is designed to be undetectable) will have design features that give it a low RCS, as opposed to a passenger airliner that will have a high… …   Wikipedia

  • Radar astronomy — is a technique of observing nearby astronomical objects by reflecting microwaves off target objects and analyzing the echoes. This research has been conducted for four decades. Radar astronomy differs from radio astronomy in that the latter is a… …   Wikipedia

  • radar — /ray dahr/, n. 1. Electronics. a device for determining the presence and location of an object by measuring the time for the echo of a radio wave to return from it and the direction from which it returns. 2. a means or sense of awareness or… …   Universalium

  • radar echo — noun an electronic signal that has been reflected back to the radar antenna; contains information about the location and distance of the reflecting object • Hypernyms: ↑electronic signal • Hyponyms: ↑blip, ↑pip, ↑radar target, ↑clutter …   Useful english dictionary

  • radar target — noun a radar echo displayed so as to show the position of a reflecting surface • Syn: ↑blip, ↑pip • Hypernyms: ↑radar echo …   Useful english dictionary

  • History of radar — The history of radar starts with experiments by Heinrich Hertz in the late 19th century that showed that radio waves were reflected by metallic objects. This possibility was suggested in James Clerk Maxwell s seminal work on electromagnetism.… …   Wikipedia

  • Continuous-wave radar — is a type of radar system where a known stable frequency continuous wave radio energy is transmitted and then received from any reflecting objects.[1]Continuous wave (CW) radar uses Doppler, which renders the radar immune to interference from… …   Wikipedia

  • Monopulse radar — is an adaptation of conical scanning radar which sends additional information in the radar signal in order to avoid problems caused by rapid changes in signal strength. The system also makes jamming more difficult. Most radars designed since the… …   Wikipedia

  • Pulse-Doppler radar — Pulse Doppler is a radar system capable of not only detecting target location (bearing, range, and altitude), but also measuring its radial velocity (range rate). It uses the Doppler effect to determine the relative velocity of objects; pulses of …   Wikipedia
