En metod för avsökning med koherent radar och en radar för genomförande av metoden

摘要

The present invention relates to a method for scanning with a coherent radar and a radar for carrying out the method. The basic object of the invention is to get small mechanical mass movements and thereby in a simple way facilitate fast scanning cycles. This is solved according to the invention by a radar comprising a transmitter, an antenna system, a receiver and a signal processing equipment. Further, the radar is caracterized in that the antenna system comprises a physical antenna having a reflector surface (A) or antenna lens and a feed system arranged to successively direct radar signals towards and/or receive radar signals from different part surfaces ( DELTA A) of the antenna or lens and that the signal processing equipment is arranged to use coherent integration of received signals.
