frequency modulation, ambiguity function, correlationAbstract
A signal with a symmetric linear frequency modulation and its properties are considered, analytic form of signal and its spectrum are shown, figures of amplitude and phase spectra of signal are drawn, figures of ambiguity diagram, cross-correlation functions and iso-response ambiguity function in strong and weak fields are shown. Considered properties of section of crosscorrelation function to two peaks and effect of these properties. Advantages and disadvantages of the signal, its application field are outlined.
