Abstract: | In order to improve accuracy and intelligibility of error prediction for one novel target system based on six-intersected-screen,which was used to measure bullet flight vector,a method based on Taguchi and Monte Carlo simulation approach other than traditional differential approach was introduced.Working principle of novel bullet location measurement system was presented.Main factors affecting the robust of system measurement accuracy were found out.The linear regression-based model was also built for system accuracy predication according to the main factors' configurations.On condition of certain structure of apparatus,error prediction of 15 mm is more creditable than what comes from traditional method,according to experiments committed. |
