Detection of concealed explosives and contraband
First Claim
1. Apparatus for detection of buried antipersonnel land mines and explosive-filled ordnance, comprising:
- a vehicle for articulatingly supporting a boom;
an x-ray generation means mounted on a first end of said boom for generating x-rays;
a detection means mounted on said first end of said boom for detecting backscattered x-rays from the earth surface and earth covered objects;
an advance control means for controlling the advancement of said boom;
an audio and visual alarm means for notifying an operator of at least the possible presence of land mines and explosive-filled ordnance mounted on a second end of said boom; and
shielding means for shielding an operator;
wherein said vehicle is positioned between said first and second ends of said boom and is remotely operated by said operation.

Abstract
The invention is a detector for detection of concealed explosives, drugs and contraband using x-rays imaging and powder pattern techniques and ultrasonics. In case of inspection of carry-on baggage a combination of computer-aided x-ray transmission imaging and x-ray diffraction analysis is used to screen; confirm and localize threats. The x-ray transmission is used to segregate dense baggage and cargo which are inspected by x-ray backscatter imaging to identify suspicious objects. All suspicious objects are carefully analyzed by x-ray diffraction. In another embodiment a slow processing system uses diffraction for identification of threats and x-ray radiography for localization of the objects. In case of drugs concealed in compartments aboard marine vessels or air crafts a hand-held x-ray system is disclosed which can be used in three modes of operation: x-ray transmission, x-ray backscatter, or x-ray diffraction dependent on the architecture of the compartment. In case of buried mines an oscillating dual-energy x-ray backscatter imaging is used for antipersonnel mines and a combination of x-ray backscatter imaging and prompt gamma detectors is used for antivehicle and antiaircraft mines. Ultrasonic detectors are disclosed for detection of explosives on persons. Also, a tracking system based on bar-code identification system and a central computer is disclosed for baggage.
