Abstract
Systems and methods can support a computational signal processing architecture for electromagnetic signature analysis and threat detection. A plurality of sensor antennas can couple a radio frequency signal into a radio receiver. The radio receiver can generate digital samples of the signal. A raw signal analysis engine can identify signal features within the digital samples, generate signal feature vectors from the identified signal features, decode signal content from the signal feature vectors, and transmit the signal feature vectors into a signal feature network. The signal feature vectors may be aggregated from the signal feature network into a signal aggregation and analysis engine. The signal aggregation and analysis engine can refine feature vectors through processing such as identifying wireless attacks according to the signal features within the signal feature vectors. One or more operator interfaces and one or more analysis databases may support these operations.
