  • Identification of carrier frequency for pulsed signals
    Patent number: 4761604
    Abstract: A method for determining the carrier frequency of a pulsed signal based upon nominal parameters for the pulsed signal input by an operator selects an algorithm based upon a duty factor calculated from the nominal parameters. For large duty factors a conventional maximum peak detection algorithm is used to identify a spectral line having the greatest amplitude as the carrier frequency. For smaller duty factors the first nulls on each side of the main lobe of the frequency spectrum for the pulsed signal are determined and used to calculate a carrier frequency. The spectral line having the maximum peak value within a window about the calculated carrier frequency is identified as the carrier frequency.
