An RF receiver receives a scattered signal stream from the region of interest. The scattered 5 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 10 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.1/8 C", - (N (N - - Ii U - L Ofi LU f I Lu Lu zII DULJm , Lm -- 1L. (00 0Z C z-j
