本文介绍以射电源和卫星作为信标,并用狄克(Dicke)型辐射计测量微波天线最洼馈源位置的方法。测量结果表明:用该方法测量微波天线的最佳馈源位置是完全有效的,与用几何光学法确定的馈源位置相比,不仅能改善旁瓣性能,而且还能提高天线增益。该方法有较大的实用价值。
This paper presents a method of measuring the position of the most-dimpled microwave source using a Dicke radiometer with radio sources and satellites as beacons. The measurement results show that it is totally effective to measure the best position of the microwave antenna by this method. Compared with the geometrical optical method, the feed position can not only improve the sidelobe performance, but also improve the antenna gain. This method has greater practical value.
