<p>The invention concerns a method for improving resistance to deliberate or accidental jamming of a receiver of spread-spectrum radio signals transmitted by polarized wave. It consists in equipping the receiver (2) with an antenna array (1) consisting of elementary antennae (1a to 1f) having at least a so-called called adapted output channel MP sensitive to the polarization of the polarized wave used for transmission, some (1b, 1d, 1e, 1f, 1g) further comprising a second so-called cross output channel CP sensitive to polarization orthogonal to that of the polarized wave used for transmission and in carrying out first individual anti-jamming processing operations by polarimetric filtering (3) on each of the elementary antennae (1b, 1d, 1e, 1f, 1g) with adapted MP and cross CP output channels, then, globally, at the level of the reception signals obtained and the reception signals of the elementary antennae (1a, 1c) without operated cross output channel CP, a second general anti-jamming processing operation by spatial filtering (4). In addition, the invention can integrate supplementary anti-jamming processing operations by temporal or spectral filtering.</p> |
