Abstract:

Provided herein is a method and system for detecting hidden dense objects in cargo containers including at least a cargo container platform with two-dimensional sensor arrays in juxtaposition therewith. The system further includes a process that estimates a weight and mass distribution data from a cargo manifest for the cargo container and available historical information about the cargo container. The historical weight and mass distribution is compared to the actual weight and mass distribution measured by the sensor arrays to detect discrepancies which will identify the tested cargo container as suspect and in need for further investigation.
