Radars are radiodetermination systems which receive the bundled signals they have themselves emitted and which are reflected by objects, subsequent to which these signals are evaluated on the basis of various criteria. Using radars allows, inter alia, distances, the angle of distances as well as objects and their movements to be determined. Radars are used both by mobile and stationary means. Examples for mobile use are on board of aircraft and ships or as vehicle-interval radars in vehicles. Stationary radars are used, for example, by the meteorological services, air traffic control, astronomy and for speed monitoring of road traffic.

Radar is an abbreviation that stands for Radio Detection and Ranging.
