The method consists in estimating the matrix of correlation +E,cir R+EE XX of the signals received on a set of N reception sensors, computing the reverse correlation matrix +E,cir R+EE XX-n, computing vectors of intercorrelation +E,cir r+EE Xd between the signals received on the set of the N sensors and a known replica signal d(k), computing a criterion of synchronization in calculating the products of the conjugate, transposed intercorrection vectors +E,cir R+EE XX-n and of the matrix of the intercorrelation vector rXdi and comparing the value of the criterion obtained with a determined threshold value 1 to place the synchronization on the sample for which the value of the criteria exceeds the threshold value eta . To estimate the Doppler shift the synchronization sequence is subdivided into a determined number of sections of symbols to carry out fast Fourier transform computations on determined intercorrelation vectors in each section.
