Proposed is a practical method of synthesizing Barker signals’ according to the compatible metric of the autocorrelation function which uses the decrease of control breaks of derivative’s value within the autocorrelation function due to the choice of equal elements of the matrix which are located pairwise in even and uneven lines corresponding to the heteropolar control breaks of the autocorrelation function’s derivative. In addition, it is taken into account that the value of control breaks of the autocorrelation function’s derivative corresponding extreme elements of the matrix is twice smaller than that of the inner elements. All in all, the change of the length if signal’s elements minimizes the side spikes of the autocorrelation function which results in the continuality of the Barker signals’ set.
Keywords: Barker signals, broadband binary phase-shift signals, synthesis on the generalized matrix of autocorrelation function (ACF), signals minimization of peaks of sides of ACF unquantized on duration
