A Method for the Real-Time Measurement of Projectile In-Bore Velocity
Abstract
Accurate projectile velocity and displacement measurements are imperative to many ballistic studies. The Interior Ballistics Division (IBD) of the Ballistic Research Laboratory (BRL) routinely uses microwave interferometry to obtain projectile displacement versus time records during the interior ballistic cycle. This report describes the setup of a microwave interferometer to obtain projectile displacement and velocity data. A discussion of some possible sources of error and the factors which limit the resolution of the measurements is also included. Finally, a novel technique is presented for processing the analog interferometer signal in real time to obtain projectile velocity.
