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
conical scanning — A radar scan pattern in which a point on the radar beam describes a circle at the base of a cone. This type of scan pattern provides both elevation and azimuth data. The radiation pattern of the antenna is made slightly lopsided, and the antenna… … Aviation dictionary
scanning — In radar, the motion of the radar antenna assembly when searching for targets. Scanning usually follows a systematic pattern involving one or more of the following: i. In horizontal scanning (or search lighting), the antenna is continuously… … Aviation dictionary

Monopulse radar — is an adaptation of conical scanning radar which sends additional information in the radar signal in order to avoid problems caused by rapid changes in signal strength. The system also makes jamming more difficult. Most radars designed since the… … Wikipedia
Transmission electron microscopy — A TEM image of the polio virus. The polio virus is 30 nm in size.[1] Transmission electron microscopy (TEM) is a microscopy technique whereby a beam of electrons is transmitted through an ultra thin specimen, interacting with the specimen as it… … Wikipedia
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
