Aiming at the problem of quick trajectory parameters solution to given distance airburst weapon's setter,the solver method based on dimensional interpolation of ballistic parameters for fuzes'setter device was proposed.The method compared two kinds of dimensional interpolation algorithm and obtains the bilinear interpolation algorithm with the advantages of simple calculation,satisfying the accuracy and more suitable for the ballistic calculation of the setter.Simulation results showed that the distance between the burst point had a great influence on the precision of the burst point,and the altitude had little effect on the precision of the burst point.The bilinear interpolation algorithm was used to meet the requirements of the calculation and the time requirement.
