“…It is very essential to measure the spin rate of projectile moving in air. Methods used for spin measurement are cameras [7][8][9] and Doppler radar [10][11][12] . Another way to measure spin of projectiles is using the principle of induced electro-motive force (emf) in which the pickup coil generates a sinusoidal wave as the projectile passes over it 13 .…”

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

et al. 2016

<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>
