Measuring Technique of Burn-out Indices for 2.75″ Rocket Motor

2.75인치 로켓트 모터의 연소완료지표 계측기법

This paper presents the measuring technique of time and velocity when rocket motor is burnt out for 2.751" rocket. This technique use doppler effect, frequency spectrum analysis and curve fitting. In this study, we use muzzle velocity radar for doppler signal acquisition, short-time fourier transform for spectrum analysis and curve fitting for smoothing.
