摘要: 该文提出一种测量微波场功率分布的有效方法.为了定量测量强微波场功率分布,设计了测试容器及多路温度同步采集和处理系统;并构造了两种算法对采样数据进行修正处理,给出了微波场功率分布的实验结果.此方法可行、可靠,很有实用价值.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.
