开口波导有效接收面积的测量
Measurement of effective aperture for an openended waveguide
-
摘要: 讨论了用开口波导N5作为接收天线的有效面积的测量，给出了测试的原理和方法，并给出了该开口波导的有效接收面积与频率的关系的测试结果。将测试结果与俄国人标定的结果进行了比较。结果表明测试结果是可信的，为准确测试高功率微波源的输出辐射场功率提供了必要条件。该测试方法也适用于其他天线的增益和有效面积的测量。

Abstract: The measurement of the effective aperture of a waveguide antenna marked N5 is discussed in this paper. The principle and the method of measurement are presented. And the results of the effective aperture for the antenna with the corresponding frequencies are given. Compared to the results measured by Russian, the measured data is reliable. It facilitates the precisely measurement of the output power of the HPM source. The measurement method used in this paper can also be applied to measure the gain and the effective aperture of other antennas.-
