摘　　要：为了了解近程导弹在肩抗瞄准过程中的扰动运动特性,并在此基础上建立捷联惯导系统的初始对准方法,利用几何原理对瞄准过程进行试验,将试验获得的地面坐标系中的数据处理转换成捷联惯导系统应该测量到的数据,由此提出了初始对准方法、建立了数学模型、给出了算法。利用数字仿真手段验证了初始对准数学模型的正确性和可行性,研究了计算误差和测量误差。给肩抗发射的近程导弹提供了一种便捷有效的初始对准方法。For understanding the disturbing movement characteristic of short range missile in the progress of pickaback aiming at the objects, and corresponding establishing the method of initial alignment of strapdown inertial guidance system, we can test the progress by using geometry theory, and convert the data in the ground coordinate system obtained by testing to the ones in the strapdown inertial guidance system accordingly. Thereout, we can bring forward the method of initial alignment, and establish mathematics model and algorithm. Using digital simulation, we can also validate the correctness and feasibility of initial alignment of the mathematics model, research the calculating error and the measuring error. A more efficient method of initial alignment can be offered to the short range missile by shooting pickaback.
