  • Apparatus and method for detecting and inhibiting signals interfering with a Loran C signal
    Patent number: 4392138
    Abstract: An interference rejection apparatus is provided which samples the Loran C signal at selected pulse tracking reference points. The Loran C samples are separated into even and odd groups by appropriate summing-weighting circuitry. The even pulse and odd pulse waveforms thus produced are analyzed to determine the presence of an interfering signal which corrupts either of the off or even pulse groups. Upon detection of interference with either the even or odd Loran C samples, strobe dropping is employed to reject the affected group of samples.
