Radar is extremely effective at spotting enemy aircraft and ships—somuch so that military scientists had to develop some way around it! Ifyou have a superb radar system, chances are your enemy has one too. Ifyou can spot his airplanes, he can spot yours. So you really needairplanes that can somehow "hide" themselves inside the enemy's radarwithout ...
Radar can be traced back to a device called a Telemobiloskop(sometimes written French-style, Télémobiloscope), invented in 1904by German electrical engineer Christian Hülsmeyer(1881–1957). After hearingabout a tragic collision between two ships, he figured out a way to use radio waves to help themsee one another when the visibility was poor. Artwor...
Radar can be used to help study severe weather events such tornadoes and hurricanes, or long-term climate processes in the atmosphere. Ground-based Research Radar The NCAR S-Band Dual-Polarization Doppler Radar (S-PolKa) is a 10-cm wavelength weather radar initially designed and fielded by NCAR in the 1990s. Continuously modified and improved ...
Weather radar, also called weather surveillance radar ( WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the ...

Radar is a system that uses radio waves to determine the distance ( ranging ), direction ( azimuth and elevation angles ), and radial velocity of objects relative to the site. It is a radiodetermination method [1] used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain.
Jan 10, 2022 · Radar – which stands for Radio Detection and Ranging – is a detection system that uses radio waves to locate objects. It is still widely used today, but as technology has advanced they now ...
Mar 25, 2024 · radar, electromagnetic sensor used for detecting, locating, tracking, and recognizing objects of various kinds at considerable distances. It operates by transmitting electromagnetic energy toward objects, commonly referred to as targets, and observing the echoes returned from them. The targets may be aircraft, ships, spacecraft, automotive ...
