摘要:
本文介绍了雷达天线罩电气技术性能参数中的功率传输系数瞄准误差 (BSE) 及瞄准误差抖率后, 由天线罩外形的几何关系, 导出了平均入射角的计算公式, 并给出某种陶瓷天线罩入射角的计算结果( 入射角I和天线视角 的关系曲线) , 推导了无耗介质天线罩按最佳传输考虑求天线罩顶部等壁厚的理论计算公式; 并根据相位衬称原理, 导出了设计天线罩后部变壁厚规律的公式, 最后给出按上述方法设计的某种陶瓷天线罩之实测BSE 曲线、|T|2 曲线.
Abstract:
After a brief description of the electrical technical performance of radome, in particular the tpower ransmission coefficient (|T|2) the boresight error (BSE) and the slope of boresight error ,the formula for calculating the Average incident angle is derived based upon the geometrical relationship of radome configuration and the computation results of incident angle for some kind of ceramic radomes is given (the relations among the incident angle I ,apparent angle of antenna and displacement x) . Then the theoretical computation formula for isowall thickness at the top part of radome made of lossless dielectric materials is derived in accordance with the requirement of optimum transmission coefficient. The formula for the law of wall-thickness change for the designing of the rear part of radome is also obtained according to the principle of isophase symmetry. Finally,the measured characteristics of BSE and (|T|2) for a sort of ceramic radome designed according to the above method are given.
