1. A method for detecting a target having a radar including transmitter means for generating bursts of radar pulses, each scan of a radar having of a number (Nb(k)) of bursts for each scan k, the method comprising the steps of:
- a) pre-selecting a radar cell by a detection process;
b) initializing a Track-Before-Detect process upon the pre-selected cells, using a track filter to construct a validation gate associated to the next scan k+1;
c) using the data an the validation gate of scan k+1 to update the Track-Before-Detect process and using the data to construct the validation gate associated to the next scan k+2;
step (c) being repeated scan to scan.

Abstract
A radar comprising transmitter means for generating bursts of radar pulses, each scan of a radar consisting of a number (Nb) 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.
