给出了比例导引法的差分方程, 采用Matlab语言, 对比例导引法的导弹理想弹道进行了三维数据仿真, 绘制出三维理想弹道。随导弹与目标参数变化情况, 对理想弹道的特性进行了分析-Proportional navigation law gives the differential equations, using Matlab language, the ideal proportional navigation law missile trajectory simulation of three-dimensional data, draw three-dimensional ideal trajectory. With the changes in the missile and target parameters, the characteristics of the ideal trajectory were analyzed
