Device for improving the signal/noise ratio S + B1 and S + B2 coming from two aerials, comprising two correlators with polarity coincidence, whose first inputs receive chopped tensions x + y and x - y, x and y being sinusoidal voltages depending respectively on the correlation coefficients of noise B1, B2 and of the said noise put in phase coincidence, and whose second inputs receive chopped tensions S + B1 and S + B2, the required signal being collected at the output of an adder whose inputs are connected to the outputs of the said correlators.
