机载雷达天线罩的电讯性能分析

Electrical Characteristic Analysis on Airborne Radomes

在分析机载雷达天线罩的结构及外形的基础上，采用了一种高效的三角形平板离散模拟方法，并采用较为直观的几何光学射线跟踪方法推导出雷达天线罩的电讯性能的计算公式。最后将某型飞机雷达天线罩的电讯性能计算和现场测试结果作了对比，结果是令人满意的。

Presents a more efficient method of electric characteristic calculation of airborne radomes. Based on the structure and the shape of the airborne radomes they are precisely simulated by triangle elements. The calculating equations of electric characteristics such as transmission coefficient, reflex coefficient, radiation valve with radomes and radiation valve without radomes, are also derived by geometry optical raytracing method. In the end, the comparison of electric characteristics calculation and field measurement is given. The results are very satisfied.
