1. A method for a computational signal processing architecture for electromagnetic signature analysis and threat mitigation, comprising: providing a plurality of radio receivers, each associated with a unique plurality of sensor antennas; providing a plurality of raw signal analysis engines; providing one or more signal aggregation and analysis engines coupled to the plurality of raw signal analysis engines via a signal feature network; receiving unique radio frequency signal instances associated with a transmitting device into each unique plurality of sensor antennas; coupling respective unique radio frequency signal instances from each unique plurality of sensor antennas into respective ones of the radio receivers; sampling, within each radio receiver, a digital representation of the respective radio frequency signal instance; communicating each digital representation from the respective radio receiver to one or more of the plurality of raw signal analysis engines; identifying, by each respective raw signal analysis engine, signal features within the digital representation; generating, by each respective raw signal analysis engine, signal feature vectors from the identified signal features; providing a signal database to support each respective raw signal analysis engine; transmitting the respective signal feature vectors into the signal feature network; aggregating, from the signal feature network, the signal feature vectors into one of the signal aggregation and analysis engines; generating, within the signal aggregation and analysis engine, an aggregated signal feature vector from two or more signal feature vectors in response to the two or more signal feature vectors originating from the transmitting device; providing analysis databases to support the signal aggregation and analysis engine; processing, within the signal aggregation and analysis engine to identify wireless attacks according to signal features within the aggregated signal feature vector; and mitigating operation of the transmitting device in response to identified wireless attacks.
