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.
