摘要
详细分析了“聚焦法”测量天线阵列方向图的理论依据和测量原理 ,提出利用“聚焦法”测量 OS-MAR2 0 0 0天线阵列方向图的技术方案 .
There are many method to measure the pattern of phased array antenna, such as technique of phane scaning in near field, focsing method, general method in far field, etc. In this paper, the principle base and the realization method of the phased array antenna pattern's measurement with focsing method in near field zone are discussed. The patterns of near field and far field are compared through experiment. The result is indicate that this method to the phased array antenna's performance for ground wave radar is an effective method in near zone.
