摘要

摘要: 利用机械调节波导宽边尺寸可变化波导波长，从而实现变频波束扫描相同的效果，针对窄边辐射波导行波阵的波束扫描特性进行了分析，以实现宽角波束扫描为目标，着重分析了不同辐射缝隙间距下变化宽边所能得到的最大波束扫描范围。设计了通过变化宽边尺寸实现宽角扫描的X波段窄边辐射波导缝隙阵，设计波束扫描范围指向波导馈入端，避开阵列法向辐射(此方向辐射效率较低)，实现了29°的连续波束扫描范围，在波束扫描范畴内增益下降小于3 dB，辐射效率大于62%；设计缝隙宽度3 mm, 波导长度约1 m(缝隙数40)，单根波导缝隙天线可实现高功率微波功率容量70 MW。

Abstract: The wavelength of the waveguide of array antenna can be varied by mechanically adjusting the broadside size of the waveguide.Thereby adjusting the broadside size of the waveguide can achieve the same effect of beam scanning by varying feeding microwave frequency. In this paper, the beam scanning characteristics of narrow edge radiation waveguide traveling wave array antenna is analyzed. The maximum beam scanning range with the variation of the broadside size of the waveguide of array antenna under different spacing distance between adjacent radiation slots is analyzed. We designed an X-band waveguide slot array with variable broadside size of waveguide. We designed the beam scanning range point to waveguide feeding end and avoided array normal radiation (the radiation efficiency in normal radiation is low). The continuous beam scanning range is 29°. In the beam scanning range, the gain drop is less than 3 dB.The radiation efficiency is greater than 62%. The slot width of array is 3 mm, the waveguide length is about 1 m, and the number of slots in single waveguide is 40. The capacity of high power microwave of a single waveguide slots antenna can achieve 70 MW.
