Claim:
A method of eliminating an incident signal resulting from multipaths in a receiver for satellite signals, said incident signal having a received power, in the processing band, which is smaller than that of the thermal noise of the receiver, applied to an antenna constructed around an antenna main sensor and comprising an array of auxiliary sensors, these auxiliary sensors all being equidistant from the main sensor and regularly spaced apart, wherein the array of auxiliary sensors comprises 2n auxiliary sensors, with n≧3 of the method comprising the steps of determining the direction of arrival of the signal resulting from the multipaths by successively taking the pairs of auxiliary sensors symmetric with respect to the main sensor, and performing the weighted combination of the signals arising from the n sensors, the direction of the transmitter being known, and wherein for a number n sensors, a weighting by −(n−1) is performed for the main sensor, and a weighting by Ratio sym(i) is performed for each of the auxiliary sensors of rank i, followed by a summation of all the weighted values, with: Ratio ( i ) = E ( i ) E sym ⁡ ( i ) · - 1 ⅇ j ⁢ ⁢ ϕ i , in which expression E(i)=(χ i −e jφ i ·χ o ), χ i being the product between the code of the signal received on sensor i and the local code, χ o being the same product for the main sensor, e jφ i being the phase shift induced on the sensor considered by the direct signal, E sym(i) being the value homologous to E (i) for the sensor symmetric to sensor i with respect to the main sensor and Ratio sym(i) the value homologous to Ratio (i) for the sensor symmetric to the sensor i considered with respect to the main sensor.
