Abstract
The paper describes different technological efforts to demonstrate the usefulness of millimeter wave sensors for security applications. The scope of the work covers a miniature radar in a portal geometry using a near field SAR approach for passenger control and the same radar hardware with a slightly modified scanning approach for luggage inspection employing a three dimensional SAR algorithm. Another approach to detect concealed weapons and explosives is by using radiometric systems. In principle, a scanner using this technique measures the thermal noise of the radiation reflected by the body. This is equivalent to the temperature on the surface of the body. The main difficulty with this technique is the realization of a fast scanning algorithm. The status of both approaches is surveyed and typical results are discussed.
