  • Patent number: 11994602
    Abstract: The invention includes a method for calibrating at low frequency and in-flight a goniometry apparatus including an antenna array, on board an air carrier. The method includes for an angular position of reception, calibrating the airborne goniometry apparatus at a given frequency, comprising transmitting, by means of a calibration transmitter, at the given frequency and in the direction of the goniometry apparatus, at least two calibration signals, with polarizations orthogonal to each other. The method also includes measuring a response of the antenna array for each of the signals. The invention also includes a system implementing such a method.

  • Patent number: 11608589
    Abstract: A method for coating a textile material, said method includes the following steps: a) incorporating activated carbon in powder form into a coating composition including an aqueous solvent and at least one organosilicon precursor, wherein the organosilicon precursor represents from 5 to 50% by volume relative to the whole of the aqueous solvent and organosilicon precursor, b) impregnating the textile material with the coating composition by padding and c) drying the impregnated textile material, characterised in that the coating composition contains no polycarboxylic acid or catalyst.
