For Dungeons & Dragons roleplayers, part of the fun of make-believe adventure is searching for hidden chambers where the monsters keep their treasure. For that matter, it’s a familiar theme in horror movies to have villains and vampires pop out from behind walls and bookcases.
But for U.S. commandos, hidden compartments are not entertainment. They are obstacles to a successful mission to capture fugitives, or seize documents and weapons. And on a house raid in hostile territory, there isn’t a lot of time to go tapping on walls to find a stash.
That’s why U.S. Special Operations Command (SOCOM) wants a detector that can quickly spot where the loot is hidden. The goal of the research project is to develop a handheld device that can detect hidden chambers in an average-sized room (168 square feet) and at a range of about 6.5 feet during sensitive site exploitation, or SSE, operations.
