  • 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.
