Introduction. This article consist calculated ambiguity function, autocorrelation function, cross sections of ambiguity function in different planes. Statement of a problem. Is shown the requirements for the correlation functions of signals used in radiolocation. Method of creating Legandre Sequences. The algorithm of forming sequences Legendre are shown in this article. Shown the advantages of Legendre codes compared with M-sequences. Ambiguity function of Legandre Sequence. The 3D view of ambiguity function of PM signal forming by Legandre Sequence(N=257) is shown in this article. The autocorrelation function of signal is shown. The cross sections of ambiguity function at different layers is submitted. The resolutions of Legandre signal is calculated and compared with resolutions of M-sequences. Conclusion. An analysis of all correlation characteristics of PM signal formed by Legandre-sequence are shown here.Downloads
