FIELD: passengers security screen filtering.
SUBSTANCE: device comprises an aerial (1) eradiating electromagnetic waves, mostly millimeter waves, installments for spatial focusing of radiated beams and installments for waves manipulation at the precise focusing point (5) to the effect that the above point (5) serves as a mobile virtual aerial for the SAR-analyses; the devices for the spatial focusing comprise the installed rotatable focusing and defocusing quasi-optical element; the installments for waves spatial manipulation at the precise focusing point (5) incorporates the reflector (4); the quasi-optical element (3) and the reflector are mounted to rotate around the single rotation axis (8) at different angular speed.
EFFECT: enhancement of the resolution with lesser distortion and instrumental expenses.
