Lobe switching — is a method used on early radar sets to improve tracking accuracy. It used two slightly separated antenna elements to send the beam slightly to either side of the midline of the antenna, switching between the two to find which one gave the… … Wikipedia
History of radar — The history of radar starts with experiments by Heinrich Hertz in the late 19th century that showed that radio waves were reflected by metallic objects. This possibility was suggested in James Clerk Maxwell s seminal work on electromagnetism.… … Wikipedia
Conical scanning — is a system used in early radar units to improve their accuracy, as well as making it easier to steer the antenna properly to point at a target. Conical scanning is similar in concept to the earlier lobe switching concept used on some of the… … Wikipedia
AN/FPS-16 — manned space program and the U.S. Air Force. The accuracy of Radar Set AN/FPS 16 is such that the position data obtained from point source targets has azimuth and elevation angular errors of less than 0.1 milliradian (approximately 0.006 degree)… … Wikipedia
