Abstract
In order to improve the computation accuracy of the ballistics for multiple-round simultaneous-impact(MRSI)of single artillery,the local interpolation algorithm(LIA)was proposed based on 2D particle trajectory equation under standard conditions and vacuum 2D trajectory oblique-range formula. It can obviously improve the accuracy to reduce the interpolation interval and increase interpolation sequence. The MPI based parallel computation technique was used in the local interpolation algorithm. The method can effectively reduce the computation time and ensure the computation time satisfy battlefield requirements. The task allocation scheme in the parallel computation was given,and the parellel efficiency was computed. Relationship between this parallel computation efficiency and the number of CPU cores used shows that there is an upper limit on number of CPU cores of ballistic computer. The MRSI computation task was carried out with range between 5 km to 15 km to verify the validity and efficiency of the algorithm.
