1. A monitoring system that may be associated with an operational system, said monitoring system operating to monitor sources of desirable and undesirable electromagnetic emissions present in a first frequency region containing pre-determined frequency bands in which at least some of the sources may interfere with said operational system that is receiving electromagnetic emissions with specific characteristics in said pre-determined frequency bands, comprising:

  • a receive assembly capable of detecting low levels of electromagnetic emissions, said receive assembly having an input and an output;

    an antenna system operably connected to said input of said receive assembly, and a processor in operable communication with said output of said receive assembly, wherein said monitoring system receives and measures desirable and undesirable electromagnetic emissions in said first frequency region, compares said desirable and undesirable electromagnetic emissions in said first frequency region to a reference in a second frequency region separate from said first frequency region, records the results of said comparison, identifies indications of interference in said pre-determined frequency bands, and reports said indications of interference, said indications otherwise attainable only unreliably by using a spectrum analyzer or equivalent capability.
