摘要
天线罩优良的电气性能是提高导弹瞄准精度的关键所在。天线罩属于硬脆材料制成的大型薄壁复杂回转体零件,随着对其性能要求的不断提高,传统的加工安装方法,已很难保证加工出高质量的合格产品。分析了单喇叭反射测量,并详细分析了工件在多工序转换过程中,天线罩安装误差的产生过程及其对插入相位延迟参数的影响,然后针对现有安装技术中存在的问题,提出了基于主动寻位的天线罩安装方法。该方法使此类大型工件的精确定位变得方便、快捷。为导弹天线罩的电性能检测提供了一种新的安装手段。
The electric performance of radome directly affects the Boresight Accuracy of missiles. Radome is a large complicated shell solid af revolution made af hard and brittle material.With the enhance- ment of radome performance requirement, it is very hard to manufacture high quality product by the tradi- tional fixing method.Analyzed the reflection measurement based on single horn,and then the occurence of radome installation errors and the influence of errors on Insertion Phase Delay （IPD）is analyzed as well. Therefore in order to solve the problems of installation technology available ,a new method is proposed to increase the fixing precision and efficiency af this large-sized work-piece.
