Radar system for carrying out low and very low altitude coverage of area of airspace located above field of wind turbines, has element comprising antenna directed towards zenith arranged to present radiation diagram in azimuth

摘要

The system has elements i.e. transmitters (11) or receivers (12) with a echo elimination unit mounted on some of wind turbines, where the elements jointly realize a coverage of a portion of an airspace located above a field of wind turbines. A number and a position of the elements are a function of a number of the wind turbines and a surface occupied by the wind turbines. Each element comprises an antenna directed towards a zenith arranged to present an omnidirectional radiation diagram in azimuth. Signals such as periodic impulses and continuous waves, are emitted by the elements.
