its precision is influenced by the projectiles attitude. Study on the velocity measurement precision influenced by projectiles attitude
theoretical model of inductive-type coil target with different attitude is established
and calculate variation of induced electromotive force( EMF) with different yaw angle
pitching angle and variation of offset using software Matlab. Then
the model is verified by experiments. The calculation results indicate that the error of projectiles attitude is up to 0. 511 % when the standoff distance is 1 m
and the yaw angle is more important. Modeling result can provides theoretical reference and advice for fair use and error compensation.
