More Information
Summary:The present invention relates generally to security surveillance systems using electromagnetic radiation, and more particularly to the use of microwave radiation to detect contraband hidden inside of a non-metallic container, such as a vehicle tire. The present invention relates to a method and system for using microwave radiation to detect contraband hidden inside of a non-metallic container, such as a pneumatic vehicle tire. The method relies on the attenuation, retardation, time delay, or phase shift of microwave radiation as it passes through the container plus the contraband. The method is non-invasive, non-destructive, low power, and does not require physical contact with the container.
