Aiming at the problems existing in common measurement methods of fragment velocity and scatter peculiarity, the integrated measurement method of fragment velocity and scatter peculiarity is studied, and an array-type integrated measurement system is designed in this paper. The integrated measurement system takes the comb target as the array element to construct the measurement target. Based on the multi-channel synchronous timing method, the flight time and target location of fragment are obtained. Combined with the correlation measurement principle, the fragment velocity and scatter peculiarity are obtained. The validation test result shows that the system can realize the integrated measurement of fragment velocity and scatter peculiarity. In the measurement of fragment scatter peculiarity, compared with the results of manual statistics, the fragment capture rate and the measurement accuracy of distribution density is improved by at least 3%, and the measurement error of scatter Angle is less than 5%. It verifies the feasibility of the integrated measurement system and the reliability of the measurement results. The system provides an effective measurement method for the integrated measurement of fragment velocity and scatter peculiarity.
