摘要
天线罩设计是一项具有挑战性的工作。结合某型吊舱天线罩设计任务,本文采用等效平板原理分析了天线罩电透过性能,并在此基础上对天线罩进行了电设计,运用几何光学—射线跟踪方法分析了天线罩的引入对天线辐射特性的影响,给出了方向图和透波率的测试曲线,很好的达到了设计指标要求。目前该型天线罩已投入使用,性能良好。
Design on the radome is a challenging task. Combined the design work on some type cabin radome, this paper analyzed the transmission characteristic utilizing the equivalent plane principle, then designed on the electrical aspect. Utilized the geometry optical-ray tracing method to analyze the influence of the radome on the antenna radiation characteristic. Offered the test curve of the pattern and the transmission rate, and met the requirement of the target. Now this kind of radome has been employed, and showed excellent performance.
