Abstract
A method for identifying a warhead in an aircraft launch tube includes providing a pattern of grooves on the surface of a warhead, with the pattern of grooves being associated with an identification code identifying the warhead or a characteristic of it, providing the warhead in an aircraft launch tube, providing a piezoelectric transducer on the launch tube, emitting an ultrasonic wave from the piezoelectric transducer to the pattern of grooves, where the wave encounters the pattern of grooves at an angle of less than 90° so that waves striking the interior of a groove are reflected back to the transducer as echo waves, while waves not striking the interior of a groove are reflected away from the transducer, and reading the pattern of returning echo waves to determine the identification code indicated by the pattern of grooves on the warhead.
