摘　　要：机载红外扫描仪黑体温度测量是遥感数据定量化反演的依据,已经成为仪器设计的重要环节。由于黑体的面积较大,相对于目前一般使用的单点测温方法介绍一种多点测温方法,在黑体内放置多个温度传感器,通过扫描网络实现多点巡回测温,提高黑体测温准确度。同时,兼容多种不同精度的温度传感器,能够适应不同灵敏度的红外扫描仪对黑体测温精度的要求。The blackbodies temperature measuring data is the base for remote sensing data retrieval, and the temperature measuring is an important part in system design. A multipoint temperature measuring method is presented, and compared with the common single point temperature measuring method. As the area of the blackbody is wide, in which several temperature sensors are placed. These sensors are scanned one by one to measure temperature, in such a way the temperature measuring veracity shall be improved. The system is also compatible for multiple sensors with different measuring precision, to meet the needs of different infrared scanners.
