1. A method, comprising:

  • analyzing, by a system including a processor, a wide frequency band with respect to signal power levels in specified narrow frequency bands;

    detecting, by the system, narrow frequency band signal power levels received in the specified narrow frequency bands;

    determining, by the system, an average composite wideband power level associated with the narrow frequency band signal power levels;

    determining, by the system, an adaptive threshold;

    detecting, by the system, narrow band interference in the wide frequency band according to the adaptive threshold, the average composite wideband power level, or both;

    responsive to a detection of the narrow band interference, obtaining, by the system, identification information for a source of the narrow band interference, wherein the obtaining of the identification information for the source of the narrow band interference comprises intercepting a transmission from the source that includes the identification information without requesting the transmission; and

    initiating, by the system, a strategy for responding to interference in the wide frequency band caused by the detected narrow band interference, wherein the initiating of the strategy is according to the identification information.
