摘要: 該文提出一種測量微波場功率分布的有效方法.為了定量測量強微波場功率分布,設計了測試容器及多路溫度同步采集和處理系統(tǒng);并構造了兩種算法對采樣數(shù)據(jù)進行修正處理,給出了微波場功率分布的實驗結果.此方法可行、可靠,很有實用價值.Abstract: A method to effectively measure the microwave field distribution is proposed in this paper. Firstly, to quantitatively measure the intense microwave field power distribution, a measurement container and a multiplex temperature sampling and processing system are designed. Then two algorithms are manipulated to make adjustment to the sampling data. Experimental results of power field in microwave field are provided. It is feasible, dependable and also valuable for practice.
