Electromagnetic spectrum management system

A system for transmitting a wireless countermeasure signal to disrupt third party communications comprising:

• a receiver configured to process a received wireless signal to create a processed received signal data;
• a spectrum control module configured to subtract known source signal data from the processed received signal data to generate unknown source signal data, the unknown source signal data based on unknown wireless signals;
• and
• a transmitter configured to process the unknown source signal data to create countermeasure signals and transmit a wireless countermeasure signal to thereby interfere with the unknown wireless signals.

A method for generating and transmitting an electronic countermeasure signal based on active frequency spectrum comprising:

• receiving wireless signals within a frequency band during a first time period, the received wireless signals representing wireless activity within the frequency band;
• converting the received signals from a time domain to a frequency domain to determine frequencies at which wireless activity is occurring;
• determining frequencies at which friendly communication is occurring, the friendly communication defining friendly frequencies;
• removing the friendly frequencies from the frequencies at which wireless activity is occurring to establish unknown source signal frequencies;
• converting the unknown source signal frequencies to the time domain to establish unknown source countermeasure signals;
• transmitting the unknown source countermeasure signals as wireless signals to interfere with unknown communications while not affecting friendly communication.
