摘　　要： 平台瞄准棱镜组件是平台方位光学瞄准的基准,用于全箭初始对准,其安装精度的稳定性会直接影响火箭的落点精度。分析了影响瞄准棱镜安装精度稳定性的几种原因,找到其关键因素,并针对影响精度稳定性的关键因素提出了改进设计的方法,并进一步通过试验验证,证实了设计改进的正确性。 The aiming prism assemble which is used for initial aiming of the rocket is the benchmark of the optic aiming for the direction and position of the inertial platform.The precision of the installation of the aiming prism assemble is of great importance to the CEP(Circular Error Probability)of the rocket.Some reasons which could affect the precision and stability of the installation of the aiming prism assemble are analyzed and the crucial reason is given in this paper.The improved design is suggested based on the crucial reason studied above.At last the experiment is performed which testifies that the proposed design in this paper is correct.
