Abstract
A multi-sensor signal fusion apparatus is provided for automatic modulation classification of weak unknown signals in non-cooperative communication environment with a more accurate description of the signal. The multi-sensor non-cooperative demodulation device combines a group of sensors, a signal fusion sensor, a means for signal demodulation, and a means for automatic modulation classification. An output of the signal fusion sensor is sent to a means for modulation scheme classification to select the appropriate demodulation technique for demodulating the unknown signal and provide the necessary intelligence about the monitored signals to the user and allow the user to simulate the unknown non-cooperative signal. The present invention also contemplates a multi-sensor signal fusion article of manufacture with a storage medium encoded with machine-readable computer program code for more accurate descriptions of monitored signals and methods for achieving higher accuracy descriptions of monitored signals in a non-cooperative environment with multi-sensor non-cooperative demodulation.
