The construction of in-service assessment index for armored equipment is the starting point for the implementation of in-service assessment. Armored equipment does lack an in-service assessment index system which is closely integrated with the actual work of the army.

The traditional ballistic trajectory extrapolation method uses the point mass trajectory equations to extrapolate and the extrapolation accuracy may be reduced when the extrapolation distance is too long. To solve this problem, a ballistic trajectory extrapolation method based on genetic algorithm is proposed. The radar trajectory measurement information with only position and velocity data is analyzed and processed starting from the six degree of freedom(6-DOF) trajectory equations. The genetic algorithm is applied to identify the projectile attitude angle in real time using the trajectory continuity of adjacent measurement points. A six degree of freedom trajectory extrapolation method based on genetic algorithm is established and the trajectory impact point is extrapolated. The results of simulation and experiment demonstrate the validness and feasibility of the proposed method. The proposed method can also be extended to other trajectory extrapolation models such as four degrees of freedom and five degrees of freedom and provides a new technical support for accurately extrapolating the impact point of projectile and improving the accuracy of fire control.
