A method for determining the azimuth of a target by means of an asr - radar

摘要

The present invention relates to a method of determination of the azimuth of a target by a radar, in particular of the type tc. The radar transmitting a wave of detections by bursts of pulses, it comprises at least the following steps in a burst: - a stage where the burst is divided into at least two half - bursts, a burst of a burst front and rear; - a filtering step of the half - bursts to associate a value of the azimuth angle θ1 and an amplitude value a1 to the burst, and a value of the azimuth angle θ2 and an amplitude value a2 to the burst the rear; - a stage of production of the azimuth az of the target as corresponding to the maximum of a gaussian (31) passing through the points of the components (θ1, a1), (θ2, a2). The present invention applies in particular for surveillance radars, for example used in applications for the management of the air traffic.
