Abstract: A method to determine a target azimuth with a radar. The radar sends out a wave of N-pulse bursts. The method includes in one burst: splitting up a N-pulse burst into two half bursts, of a front burst and a rear burst; filtering the front and rear bursts to associate an azimuth value &thgr;1 and an amplitude value A1 with the front burst, and an azimuth value &thgr;2 and an amplitude value A2 with the rear burst; and obtaining the target azimuth Az at a value corresponding to a maximum of a Gaussian curve passing through points having components (&thgr;1, A1) and (&thgr;2, A2).

Abstract: Disclosed is a method to determine target azimuth by the use of a radar, especially of the ASR type. The radar sends out a wave of detections by N-pulse bursts. The method comprises at least the following steps in one burst: a step in which the burst is split up into two half bursts, one front burst and one rear burst; a step for the filtering of the half burst to associate an azimuth value &thgr;1 and an amplitude value A1 with the front burst, and an azimuth value &thgr;2 and an amplitude value A2 with the rear burst; a step to obtain the target azimuth Az at a value corresponding to the maximum of a Gaussian curve passing through the points having components (&thgr;1, A1), (&thgr;2, A2). The invention can be applied especially to surveillance radars used, for example, in air traffic management applications.
