Error Analysis in Spin Measurement using Synchro-ballistic Method and its Improvement

In: Defence science journal: DSJ, Band 66, Heft 3, S. 236

Abstract

<p>Error analysis of spin measurement using synchro-ballistic method is presented in this paper. Error in the spin measurement varies as the projections of marker move away from axis of symmetry, and the reason for variation of error is explained. An improvement to synchro-ballistic method is proposed for spin measurement, which reduces the error in measured spin, and an algorithm for implementation of same is provided. Results of improved synchro-ballistic method are compared with the theoretical estimation of spin from muzzle velocity.</p>
