摘要
叙述了最近研制成功的５ｍｍ微波辐射计系统，此辐射计系统用于遥感大气中的氧气。在辐射计中采用了全功率型接收机和周期定标技术，且采用了一种新方法来稳定系统增益，提高测量灵敏度。整个系统由ＰＣ计算机控制，天线可在方位平面和俯仰平面扫描。接收机的输出由ＰＣ计算机采集并存储，在ＰＣ计算机上进行数字处理，反演出大气的信息。整个测量过程在计算机上实时显示。
The paper describes a 5mm microwave radiometer system,which will be used to re-mote sense atmosphere.Atotal-power receiver is used and periodic calibration technolo-gy is adopted in this system,and a computer is also used to sample the output of the receiv-er and to scan the antenna,which can be scanned at azimuthal plane and at pitching plane.Measured data are stored in the computer and are digitally processed to get rid of noise andto get atmospheric information. The whole measuring prograln is really timedisplayed onthe screen.
