In this paper, the precise initial guidance law based on velocity gain guidance and the state transition matrix for orbi摘要对于轨道拦截问题，给出了一种基于速度增益制导和状态转移矩阵的精确初制导方法。
This technique is also known as Test Requirements Definition technique (as are Control Flow graphing, State Transition A因果法又被称为测试需求定义方法（控制流图，状态转换分析等等），而并非测试设计。
