A system includes: a radar scanner disposed to scan the interior of a container an interrogator in communication with the scanner and a processing system in communication with the interrogator, in which the processing system displays information about the interior of the container. A method includes: mounting a radar scanner antenna to a container so as to scan the interior of the container connecting a coupler to the scanner so that the scanner communicates scanning data via the coupler to the exterior of the container. Another method includes: coupling an interrogator and radar processing system to a scanner mounted on a container and processing radar scan data from the interior of the container. Another method includes: linking a radar processing system via a communications link to an interrogator that is coupled to a scanner mounted on a container and processing radar scan data from the interior of the container.
