  • Noise jammer discrimination by noise modulation bandwidth
    Patent number: 4642644
    Abstract: A method for distinguishing between multiple noise jammer sources having different noise modulation bandwidths. Noise signals are detected by a receiver having a bandwidth substantially the same as the bandwidth of the jammer noise source. The dwell time of the noise pulses formed by the receiver provides a means for determining the noise modulation bandwidth of a noise jammer source.

  • Noise jammer discrimination by noise spectral bandwidth
    Patent number: 4642643
    Abstract: A method for distinguishing between multiple noise jammer sources having different noise spectral bandwidths. Noise signals are detected over a relatively narrow detection bandwidth. The percent of time that the jammer spectral noise is within the fixed detection bandwidth is used to estimate the jammer spectral bandwidth.
