   How does radar work?

   • Radar typically involves the radiating of a narrow beam of electromagnetic energy into space from an antenna ( see the figure ). The narrow antenna beam scans a region where targets are expected. When a target is illuminated by the beam, it intercepts some of the radiated energy and reflects a portion back toward the radar system.

   How does a tracking radar work?

   • A dedicated tracking radar —one that follows automatically a single target so as to determine its trajectory—generally has a narrow, symmetrical “pencil” beam. (A typical beamwidth might be about 1 degree.) Such a radar system can determine the location of the target in both azimuth angle and elevation angle.

   How does a radar antenna work?

   • When a target is illuminated by the beam, it intercepts some of the radiated energy and reflects a portion back toward the radar system. Since most radar systems do not transmit and receive at the same time, a single antenna is often used on a time-shared basis for both transmitting and receiving.

   How does aircraft surveillance radar work?

   • An aircraft-surveillance radar generally employs an antenna that radiates a “ fan ” beam, one that is narrow in azimuth (about 1 or 2 degrees) and broad in elevation (elevation beamwidths of from 20 to 40 degrees or more). A fan beam allows only the measurement of the azimuth angle.
