Electromagnetic Spectrum Management System

摘要

A system for transmitting a wireless countermeasure signal to disrupt third party communications is disclosed that include an antenna configured to receive wireless signals and transmit wireless counter measure signals such that the wireless countermeasure signals are responsive to the received wireless signals. A receiver processes the received wireless signals to create processed received signal data while a spectrum control module subtracts known source signal data from the processed received signal data to generate unknown source signal data. The unknown source signal data is based on unknown wireless signals, such as enemy signals. A transmitter is configured to process the unknown source signal data to create countermeasure signals and transmit a wireless countermeasure signal over the first antenna or a second antenna to thereby interfere with the unknown wireless signals.

1. A system for transmitting electronic countermeasure signal to disrupt third party communications comprising:
an antenna configured to receive radio frequency signals representing active communication during a first time period; an analog front end configured to process the received signals; an analog to digital converter configured to convert the received signal to received signal data; an FFT unit configured to transform the received signal data from the time domain to a frequency domain signal data; a spectrum control module configured to receive the frequency domain signal data and known source signal data and subtract the known source signal data from the frequency domain signal data to generate unknown source signal data; an inverse FFT unit configured to process the unknown source signal data to a time domain electronic countermeasure signal; a digital to analog converter configured to convert the time domain electronic countermeasure signal to an analog electronic countermeasure signal; an transmit amplifier configured to amplify the analog electronic countermeasure signal to create an amplified electronic countermeasure signal and present the electronic countermeasure signal to the antenna for transmission during a second time period.
