A “sticky bomb” is a type of improvised explosive device (IED) placed on a
motor vehicle by (for example) a terrorist. The bomb is typically attached with
adhesive (“duct”) tape, or with magnets. This paper reports some preliminary
results for a very rudimentary demonstration of two techniques for detecting the placement of a sticky bomb on a motor vehicle. There are other possible security applications for these techniques as well.
