In many gun accuracy investigations the projectile as well as the muzzle dynamics during shot exit must be determined. Not every instrumentation used for gun barrel motion measurements is suitable for the obtainment of the muzzle motion due to temporal resolution and spatial accuracy requirements. An instrumentation referred to as the Schmidt Displacement Transducer SDT has recently been developed at the Ballistic Research Laboratory which is well suited for these type of measurements. This report contains a brief review of instrumentation applicable to the measurement of barrel and muzzle motion, a description of the SDT instrumentation and its application for monitoring muzzle motion, an analysis procedure for SDT type of data for extracting the muzzle motion with respect to the ground, and the developed computer data analysis program with appropriate examples.
