    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.

    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...

  2. 4 days ago · Radar, electromagnetic sensor used for detecting, locating, tracking, and recognizing objects of various kinds at considerable distance. It operates by transmitting electromagnetic energy toward objects, commonly referred to as targets, and observing the echoes returned from them.

  3. For best radar performance there should be a clear line-of-sight to the target and a low level of clutter around the target. Explains the essential aspects of modern radars in simple terms, such as: antennas, clutter, Doppler speed measurement, FMCW, RCS, reflections and microwaves.

  4. Doppler weather radars are remote sensing instruments and are capable of detecting particle type (rain, snow, hail, insects, etc), intensity, and motion. Radar data can be used to determine the structure of storms and to help with predicting severity of storms.

  5. Oct 19, 2023 · Radar is a wireless technology that uses radio waves to detect the direction, speed, shape, range, and other characteristics of distant objects. The earliest use of radio waves to detect an object can be traced to the start of the 20th century.

  6. Weather radar is one of the most successful observing systems for scanning the skies and monitoring for rain, snow, hail, damaging winds, and tornadoes. Weather radar monitors for these weather events by providing information on precipitation type, intensity, and movement.
