摘　　要：文中采用球谐函数法计算扰动引力,在被动段标准弹道的基础上,建立了被动段干扰导弹模型。分别选取了近程、中程、远程导弹的三条被动段弹道进行仿真,计算了360阶、540阶、720阶和1080阶位系数下的扰动引力对不同射程的被动段弹道的影响。分析了扰动引力引起的落点偏差,仿真结果具有重要的参考价值。The article adopted the way of the ball function to calculate the interferential gravity. On the base of the stand- ard passive ballistic trajectory, I have established the model of the interferential passive ballistic trajectory. I chose the three ballistic trajectories to calculate. I counted that the interferential gravity which was accounted on the base of 360 steps,540 steps,720 steps and 1080 steps influenced the passive ballistic trajectory about the different field of fire. And I analyzed that the interferential gravity brought the warp of the field of fire. The result is worthy.
