Research on rapid prediction method of projectile impact point

In the test of explosion height and dynamic parameters, pre-obtaining the relatively accurate position of the projectile is essential. However, at present, it is impossible to provide a forecast value for the impact point of each projectile through methods such as firing table, gun position reconnaissance and calibration radar or ballistic radar. In order to improve the fast and accurate prediction ability of projectile impact point and realize the accurate prediction of each projectile, this paper proposes a method of establishing simulated ballistic trajectory based on the measured data of the gun position and secondary correction of the ballistic data based on the ballistic radar. Compared with the traditional method, the method has a more accurate prediction of the coordinates of the impact point due to the use of the measured data of the gun position and the radar. The test results show that after using this method, the entire forecast time can be controlled within 8 seconds, and the accuracy of distance and direction is improved. The equipment in the bomb drop area can complete corresponding actions according to the forecast data, and improve the data admission rate.
