摘　　要：本文简要介绍了真比例导引原理,建立真比例导引律的三维运动学方程,利用4阶龙格库塔法,分别计算分解在水平面上和铅垂面上的导引弹道,合成三维弹道。仿真结果与理论分析相符,验证了将三维导引弹道投影分解计算的可行性,算法通过C语言实现,具有较强的移植性。The true proportional guidance principle is briefly presented and 3 D kinematics equation of true proportional guidance law is established. The guidance trajectory decomposed in horizontal and vertical plane is calculated respectively by using fourth-order Runge-Kutta algorithm to synthesize 3D trajectory. The simulated results are accordance with theoretical analysis, which verifies feasibility of decomposition computing 3D guidance trajectory projection. The implementation of algorithm is based on C language, and it provids powerful portability.
