A receiver of signals likely to be disturbed by an interfering signal, the receiver includes an interference rejection filter comprising a multiplying gain applied respectively to an in-phase channel and an in-quadrature channel of a signal received by the receiver, the value of the multiplying gain being determined by a nonlinear function K(&#x3c1;) of the modulus &#x3c1; of the received signal, the function K(&#x3c1;) being determined so as to maximize the signal-to-noise ratio after application of the multiplying gain and demodulation of the received signal.

Receiver of signals, in particular of GNSS signals, comprising an interference rejection filter, and associated method

The general field of the invention is that of optical lidars comprising an optical porthole and operating at a first wavelength. The optical porthole of the lidar according to the invention comprises a layer or a sheet made of an optical material. The lidar comprises means for illuminating said layer or said sheet at a second wavelength different from the first wavelength, said material being transparent at the first wavelength and absorbent at the second wavelength, said second wavelength being located in the visible spectrum.
