CPC G01S 7/38 (2013.01) [G01S 7/024 (2013.01); G01S 7/36 (2013.01)] | 9 Claims |
1. A method for confusing the electronic signature of a signal transmitted by a radar, comprising the generation by the radar of a plurality of pulses, wherein the method comprises a step of modulation, in the pulse, of the polarization of the transmitted signal, according to two orthogonal or opposite polarizations, the modulation of the polarization being performed according to a predetermined modulation code, the modulation code being temporally inverted from one pulse to the next.

8. A transmission/reception device configured to implement the confusion method according to claim 1, and comprising:
a first reception channel suited to a first rectilinear polarization corresponding to a first polarization component (Ex) of the polarization of the transmitted signal; and
a second reception channel suited to a second rectilinear polarization corresponding to a second polarization component (Ey) of the polarization of the transmitted signal;
a correlator common to the first reception channel and to the second reception channel, and configured to perform a filtering suited to the modulation code.
