结构变形对抛物面天线旁瓣性能的影响

结构变形对抛物面天线旁瓣性能的影响

内容简介：由于天线结构局部变形并出现凹区，造成口径场产生畸变，从而导致了天线旁瓣性能下降。文章以某车载雷达天线为例，根据其在微波暗室的测试结果以及天线方向图与其口径场之间的关系，通过理论分析，探讨口径场分布影响天线旁瓣性能的主要机理。

Abstract：A local deformation of antenna structure and the pit occur, causing distortion of the field aperture, resulting in performance degradation of the antenna sidelobe. This article, taking a mobile radar antenna as an example, explores the main mechanism of the distribution of aperture field to the antenna sidelobe performance by analyzing the test results in microwave anechoic chamber and the relationship between antenna pattern and its field aperture.
