摘要
天线方向图是描述天线性能的重要参数,对于有源相控阵天线而言,其方向图的测试通常是一项复杂而又艰巨的工作。为适应多频点、多通道有源相控阵雷达天线测试的需要,文中提出了一种基于频率高速捷变、多通道并行处理的远场测试方法。该方法能够有效地降低测量时间,提高远场测试的效率。
Antenna pattern is an important parameter for describing antenna performance. With respect to active phased array antenna, testing its pattern is a complex and hard job. In order to fit requests of testing muhi-frequency and multi-channel active phased array radar antenna pattern, this paper presents a new far-field testing method based on high speed frequency agility and multi-channel parallel processing. Using this method can effectively reduce the measurement time and increase the efficiency of antenna farfield testing.
