摘要
介绍了机载雷达低副瓣偏馈抛物面无线的设计。对天线投影口径场的计算机辅助设计、天线的交叉极化、馈源方向图逼近、偏馈角选取及馈源罩设计等问题进行了讨论。最后将无线的远场测试结果与理论计算方向图作了比较。
The design of an airborne off-set parabolic reflector antenna with low sidelobes is discussed. The CAD of amplitude distribution in projective aperture , cross-polarization of this antenna,the pattern approximation for feed source ,off-set angle and cover are included. And finally the comparison results between measured and calculated far-field antenna patterns are given too.
