phase plane trajectory

First , proper initial conditions between ekv and target are the premise of hit - to - kill . capture region is described by equations of relative motion defined in modified polar coordinate while phasetrajectory graph is introduced . and the disturbance of initial condition biase is analyzed by cadet through statistical linearization of ekv dynamical model
本文在修正极点坐标系中建立拦截器和目标之间的相对运动方程,结合相平面轨迹图,分析了大气层外动能拦截器的拦截区;对大气层外动能拦截器动力学模型进行统计线性化,采用协方差分析描述函数法,分析了初始状态误差对弹道的影响。
