Uhf radar system for implementing a method of eliminating vegetation clutter

Abstract

A system includes a pulsed UHF radar for integrating the signal received over a given integration time. The integration time for the received signal and the size of the distance bin are defined in such a way that, taking into account the range of speeds of the targets of interest, a moving target of interest travels only a distance shorter than the size of the distance bin from one integration period to another. Furthermore, the UHF radar implements a method of forming radar blips from the received signal to form elementary blips from the signals received over the chosen integration time and to store them from one burst to another. The method also confirms that the elementary blips formed probably correspond to targets of interest and then forms, from the confirmed elementary blips, aggregate blips, the attributes of an aggregate blip depending on the attributes of the confirmed elementary blips from which the aggregate blip stems. The method also validates the aggregate blips formed, the validation of an aggregate blip depending on the distance measurement associated with this blip. The transmission of parasitic blips is reduced, brought about by the detection of echos relating to the movement of vegetation due to the action of the wind, to the tracking means.
