Abstract: In a system for locating a plurality of objects and obstructions and for detecting and determining the rolling status of moving objects, such as aircraft, ground vehicles, and the like, in the area of an airport, a short-range radar network is provided having at least three radar stations. Via simple stationary non-rotating transmitting antennas with coherent time-pulsed microwaves or other microwave signal forms, a large sector in the azimuth of about 90.degree. is illuminated, and the associated fixed receiving antennas, which have fixed subdivided sector characteristics, with one receiving channel per subsector, also receive signals from the other stations for bistatic measurements. The separation of the signals of individual stations is effected by selecting different frequencies, or alternatively, a time triggering of transmitted signals and receiver gates or by station-specific modulation codes. Illumination zones are chosen so there are no shadow zones caused by, e.g., buildings.
