radar antenna

radar antenna

[′rā‚där an′ten·ə]
(electromagnetism)
A device which radiates radio-frequency energy in a radar system, concentrating the transmitted power in the direction of the target, and which provides a large area to collect the echo power of the returning wave.

According to the announcement released on March 26, Raytheon Co., Indianapolis won the US$49,989,867 bid to provide radar antenna system overhauls, coatings, shipboard installations and incidental technical support services to Taiwan for its various Radar Restoration Program systems.
The study grew out of Moisseev's daily habit of examining scans taken from the radar antenna at the UH campus.
Some of Lando's and his constituent's assignments included the design of the electro-hydraulic drive system for the Nike-Zeus missile track radar antenna for the Nike-Zeus missile system and the Tellstar Project, the first U.S.
As a continuation of demonstrated quality, reliability, and safety-critical systems, software, and electronic hardware engineering expertise, CERTON engineers will be responsible for writing, debugging, and reviewing, running, and analyzing all Test Cases, Test Procedures, and Test Results for Validation and Verification of the Weather Radar Antenna Unit, Digital Receiver, and Antenna Controller.
Primary is commonly referred to as "skin paint." Radio waves shoot out from a rotating radar antenna, bounce off the "skin" of whatever they hit, and return to the antenna.
In July, a swift caused damage to a plane's radome - which protects a plane's radar antenna. At some UK airports, collisions with birds were serious enough for pilots to declared mayday, including a "ight which had to be aborted at Heathrow last March when the pilot had to jettison fuel and return to the London airport unexpectedly.
Sometimes disappearing between radar antenna passes.
Airbus Defence and Space engineers supported European Space Agency (ESA) technicians who worked through the night at the satellite control centre in Darmstadt to unfold and lock the solar panels and the five-part, 12.3-metre-long radar antenna in several stages.
By measuring the time the signal takes to return, it calculates the distance from the radar antenna. The farther a plane is from the radar, the less accurate it is.
A radar antenna on the ground sends electromagnetic waves that reflect from the surface of an aircraft and almost instantly return, allowing controllers to calculate how far away a plane is.
