Abstract: 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 Ki(ρ) of the modulus ρ of the received signal, the function Ki(ρ) being determined so as to maximize the signal-to-noise ratio after application of the multiplying gain and demodulation of the received signal.

Abstract: 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.
