【摘要】 根据温度与透镜天线焦斑之间的对应关系,用红外热像测温方法对自行设计的毫米波介质透镜天线的焦斑进行了测量,经分析计算,得到了透镜天线焦斑的实测值,对透镜天线焦斑焦距的设计值进行了修正,实现了毫米波的定位定功率密度辐射。与其它测温方法相比,用红外热成像方法测透镜天线焦区场分布具有准确测量局部温度、温度分布及热图像处理等优点。更多还原

【Abstract】 According to the relationship between temperature and the focal spot of lens antenna,the focal spot size of homemade millimeter wave dielectric lens antenna was measured by infrared temperature measurement technology.The experimental result,which was regard as the actual value,was achieved through analyses and calculations,and its designed value was corrected with it,then the exact radiation of millimeter wave was achieved.As a specialized technology,the infrared temperature measurement method is more accurate in some aspects compared with other temperature measurement methods,such as measuring the local temperature exactly,simulating the temperature distribution and processing the thermal image etc.更多还原
