Simulation and Analysis of Measurement Method for Projectile Axial Acceleration by MEMS Sensor

Abstract:

Measurement of axial acceleration is necessary for projectile range prediction. Three measurement methods, dual-accelerometer configuration, dual-accelerometer filtering and direct filtering, are used to eliminate acceleration measurement errors caused by accelerometer configuration location, installation errors and space rotating of projectiles. Based on six-degree ballistic trajectory model, the three measurement methods of projectile axial acceleration are simulated, and the simulation results show that standard deviation of dual-accelerometer configuration measurement error is 35.7318, while standard deviation of dual-accelerometer filtering measurement error is 2.2958 and direct filtering measurement error is 0.3344.
