   How does a radar antenna work?

   • A Radar antenna is a unit that transmits radio waves and receives the echoes of these radio waves. The performance of an antenna lies in its capability to detect the exact direction in which an object is located. It is therefore important to concentrate the rays in a particular direction if we want to know the exact direction of an object.

   How does radar work?

   • Here's a summary of how radar works: Magnetron generates high-frequency radio waves. Duplexer switches magnetron through to antenna. Antenna acts as transmitter, sending narrow beam of radio waves through the air. Radio waves hit enemy airplane and reflect back. Antenna picks up reflected waves during a break between transmissions.

   How does a radio antenna work?

   • Antenna acts as transmitter, sending narrow beam of radio waves through the air. Radio waves hit enemy airplane and reflect back. Antenna picks up reflected waves during a break between transmissions. Note that the same antenna acts as both transmitter and receiver, alternately sending out radio waves and receiving them.

   Why do we need a radar antenna?

   • Radomes are generally used where relatively severe environmental conditions are experienced. The basic performance of radar can be shown to be proportional to the product of the antenna area or aperture and the mean transmitted power. Investment in the antenna, therefore, brings direct results in the system’s performance.

   Why are radio waves used for radar?

   • Radio waves are used for radar for a number of reasons: It is simple and inexpensive to generate radio waves using electronic components. Radio waves can pass through fog, rain, mist, snow and smoke. Radio waves cannot be confused with infrared energy emitted by fire, heat haze, warm objects, hot gas or the sun.

   A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects.

   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...

    The function of antennas in radar systems. The basic job of the antenna is to emit radio waves when fed with an electrical signal. Antennas are reciprocal, that is, they work just as well in reverse, so the antenna also captures radio waves and emits an electrical signal.
