Cognitive networked electronic warfare
First Claim
1. An apparatus for cognitive networked electronic warfare that includes sensing and classifying radio communications comprising:
- one or more sensor units configured to detect radio frequency signals;
a signal classifier configured to classify the detected radio frequency signals into a classification, the classification including at least one known signal type and an unknown signal type;
a clustering learning unit configured to find clusters of signal types in an unknown signal, the clusters being used to retrain the classifier and generate a new known signal type; and
a cognitive controller configured to initiate the clustering learning unit when the signal classifier classifies a detected radio frequency signal as an unknown signal type, the cognitive controller being further configured to re-train the signal classifier with the new known signal type when the clustering learning unit generates the new known signal type.

Abstract
An apparatus for sensing and classifying radio communications is provided. The apparatus includes one or more sensor units configured to detect radio frequency signals, a signal classifier configured to classify the detected radio frequency signals into a classification, the classification including at least one known signal type and an unknown signal type, a clustering learning algorithm capable of finding clusters of common signals among the previously seen unknown signals. The system is then further configured to use these clusters to retrain the signal classifier to recognize these signals as a new signal type.
