1. A method for a computational signal processing architecture for electromagnetic signature analysis and threat detection, comprising: providing a plurality of sensor antennas within an electromagnetic environment; coupling a radio frequency signal from the sensor antennas into a radio receiver; generating, within the radio receiver, digital samples of the radio frequency signal; receiving the digital samples into a raw signal analysis engine; identifying, by the raw signal analysis engine, signal features within the digital samples; generating, by the raw signal analysis engine, signal feature vectors from the identified signal features; decoding, by the raw signal analysis engine, signal content from the signal feature vectors; providing a signal database to support the raw signal analysis engine; transmitting the signal feature vectors into a signal feature network; aggregating the signal feature vectors from the signal feature network into a signal aggregation and analysis engine; providing analysis databases to support the signal aggregation and analysis engine; refining feature vectors through processing by the signal aggregation and analysis engine, wherein the processing comprises identifying wireless attacks according to the signal features within the signal feature vectors; and providing the refined signal feature vectors to support one or more operator interfaces.
