Beschreibung
Zusammenfassung:	A system and method for detecting weapons. A radiofrequency transmitter transmits an RF signal stream into a region of interest. An RF receiver receives a scattered signal stream from the region of interest. The scattered signal stream is generated in the region of interest from the radiofrequency signal stream when a target is at least partially within the region of interest. A plurality of resonant signal components are identified from the scattered signal stream. Preprocessed resonant signal components are generated by removing environmental signal components. A target assessment is determined from the preprocessed resonant signal components using a trained statistical model. A target response is triggered if the target assessment indicates that a weapon is detected on the target.
