Abstract: The invention relates to the improving of the resistance to intentional or unintentional jamming, of a receiver of spread spectrum radio signals transmitted by polarized wave. It consists in furnishing receiver with an array antenna composed of elementary antennas having at least one so-called matched output path MP sensitive to the polarization of the polarized wave used for the transmission, certain furthermore having a second so-called cross path CP sensitive to a polarization orthogonal to that of the polarized wave used for transmission and in performing first individual antijamming processings by polarimetric filtering on each of elementary antennas with matched MP and cross CP output paths then, globally, at the level of reception signals obtained and of reception signals of elementary antennas without cross output path CP utilized, a second general antijamming processing by spatial filtering. Moreover, the invention can integrate additional antijamming processings by temporal or spectral filtering.
