    摘要： A radar comprising transmitter means for generating bursts of radar pulses, each scan of a radar consisting of a number (N b ) of bursts, the method comprises, for each scan k :

    a first step, in which a radar cell is pre-selected in a validation gate ;
    a second step, in which a Track-Before-Detect processing is initialized upon the pre-selected cells, using a track filter to construct the validation gate associated to the next scan k+1 ;
    the steps being repeated scan to scan.
    The invention can be applied to surveillance radars, for example with multi-beamforming in elevation, and more generally to all kinds of radars.
