Multi-targets detection method applied in particular to surveillance radars with multi-beamforming in elevation

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.
