Patent ID: 7386034

Claim:
An antijamming method for a receiver of transmitted polarized spread spectrum radio signals, the receiver having a receive array antenna including elementary antennas having at least one matched output path MP, the antennas being sensitive to a polarization of a transmitted polarized signal, certain elementary antennas, having a second cross output path CP sensitive to a polarization orthogonal to that of a transmitted polarized signal used for the transmission, the method comprising the steps of: performing first individual antijamming processings by polarimetric filtering on each of the elementary antennas with matched MP and cross CP output paths so as to derive from each of them, by combining the signals picked up by their matched MP and cross CP output paths, a single reception signal having undergone a first degarbling, and globally performing, at the level of reception signals originating from the first individual antijamming processings by polarimetric filtering and the reception signals picked up by the elementary antennas devoid of cross output paths CP utilized, a second general antijamming processing by spatial filtering so as to derive by combining these reception signals, a reception signal having undergone a new degarbling.
