摘　　要：基于理想二体假设下的弹道方程解析式,忽略重力在拦截末段对拦截器和目标运动状态的影响,推导了空间拦截初始制导偏差与终端零控脱靶量之间的线性近似计算式,并以速度增量的大小来近似描述拦截末端主动寻的制导段的能量需求,给出了拦截末段制导最小能量需求与零控脱靶量、探测距离之间的近似关系。通过数字仿真测试了近似计算的准确性。Based on trajectory equation under the assumptions of the restricted two-body problem and neglect the effect of gravity on interceptor＇s and target＇s motion state, the linear function between the initial guidance errors and the terminal zero effort miss vector is proposed for space interception. △V is used to represent the energy required by terminal guidance, and the relation of minimal energy required of terminal guidance, zero effort miss and detection range of seeker is also given. The accuracy of the approximate calculation was tested by simulation.
