Abstract
An armed-state detector for the testing of "live" antitank mines is discld. The invention allows a user to determine, from a safe distance, if a mine is in an "active" state. A pole mounted sensor array is placed over the mine to sample the weak repetitive magnetic field that emanates from "active" mines. A hand-held, battery powered, detector box provides an audible or visual indication of whether or not the mine is "active". In addition to indicating that the mine is "active", the armed-state detector allows the user to determine the angular orientation of the magnetometer common to all antitank mines. The detector also provides a means whereby limited diagnostics can be performed on an unexploded mine. With the armed-state detector the user can determine if the fuze of an unexploded mine has been "killed" outright, or has merely failed to respond to the test stimulus.
