摘　　要：以导弹初始瞄准误差为初始小扰动,建立理想条件下速度追踪制导律制导回路模型,在此基础上求解其解析表达式。通过对解析解进行无量纲化分析,得出理想条件下的速度追踪制导律制导回路只存在一个设计参数,它是无量纲的末制导时间,该设计参数直接决定了速度追踪制导律的制导精度与法向过载的大小。通过对法向过载及终点脱靶量的分析,给出了该设计参数的取值范围。Taking initial aiming error as inertial small perturbance, we established a model of guidance loop with velocity pursuit guidance law at the ideal conditions and deduced an analytical expression. Normalizing the analytical expression, we obtained only one design parameter, non-dimentional terminal guided time, which can directly determine the guidance accuracy and the missile lateral acceleration. The scope of the parameter was given by analyzing non-dimensional lateral acceleration and missdistance.
