An integrated walk-through system (10) for detecting concealed or suspicious objects includes a portal (12) in which a person (8) may walk through without interruption; a device (15) responsive to a person's entry into the portal for generating a trigger signal to start a detection process; one or more of a dielectric scanner device (40), an x-ray scanner device (60), a metal detector device (20), a millimeter wave camera device (50a, ... 50d), and vapor collection and analysis device (30), or a combination thereof, for performing respective detection processes in response to receipt of the trigger signal, each dielectric scanner device, x-ray scanner device, metal detector device, millimeter wave camera device, and vapor collection and analysis device generating corresponding output signals (21, 31, 41, 51a, ... 51d, 61); and, a computing device (80) for receiving the output signals from each dielectric scanner device, an x-ray scanner device, a metal detector device, a millimeter wave camera device, and vapor collection and analysis device, and generating an alarm signal (85) indicating detection of a target object carried by the person.
