| Abstract: | 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. |
