Radar technology helps DHS find underground tunnels used by smugglers

The department of homeland security (DHS) announced its plan to use radar technology specifically designed to find underground tunnels along the border. Current ground penetrating radar systems are already being used by civil engineers to detect underground pipes and tunnels. These systems, however, can only penetrate a few meters beneath the ground surface and are not adequate to accurately detect smugglers tunnels, which are often located much deeper below the surface. The new radar systems being developed for the DHS by Lockheed Martin will use a lower frequency and will be able penetrate deeper below the surface. The system will consist of a sophisticated imaging system and portable radar antennas towed behind border patrol trucks. The antenna signals will then be used to “formulate a multi-colored picture of the earth” and border patrol agents will be able to clearly see the tunnels on the monitor. Lockheed Martin team will begin testing the new system this summer, along the U.S. Southwest border to see if the new ground penetrating radar system can differentiate between tunnels, rocks, and other objects in the ground. http://www.foxnews.com/story/0,2933,529643,00.html http://www.usnews.com/articles/science/2009/07/01/border-patrol-agents-to-spot-tunnels-with-advanced-ground-penetrating-radar.html
