Abstract
Exemplary systems and methods are directed to establishing a signature for a device emitting electromagnetic radiation (EMR). The system includes a radio frequency (RF) receiver, a signal processor, and a signature generator. The RF receiver samples detected EMR, generate pulses having characteristics that are a function of the EMR, and select generated pulses in a spectral band having energy above a predetermined threshold. The signal processor establishes a set of correlated pulses, computes a vector space associated with the set of correlated pulses, and compares each pulse in the set of correlated pulses to a basis of the vector space for establishing a device signature, and associates pulses having a threshold percentage of energy within the basis in a database with a device identifier.
