A new microwave radiometer system consisting of a frequency sweep-type radiometer and an ultra wideband antenna has been developed. A computer-controlled radiometer system covers the input frequency range from 0.5 GHz to 8 GHz. It can be used not only as a multispectral radiometer system whose frequencies can be chosen freely, but also as a frequency sweep-type radiometer system whose frequency is continuously swept during measurement. When an antenna is attached to a forearm, the sensitivity of the radiometer system exceeds 0.09 degree C when the integration time is 3 sec and IF bandwidth is 500 MHz. The new microwave radiometer system may be utilized for non-invasive thermometry of the human body.
一种由扫频式辐射计和超宽带天线组成的新型微波辐射计系统已被开发出来。一个计算机控制的辐射计系统覆盖从0.5吉赫兹到8吉赫兹的输入频率范围。它不仅可以用作频率可自由选择的多光谱辐射计系统，还可以用作在测量过程中频率连续扫描的扫频式辐射计系统。当天线附着在前臂上时，当积分时间为3秒且中频带宽为500兆赫兹时，辐射计系统的灵敏度超过0.09摄氏度。这种新型微波辐射计系统可用于人体的非侵入式温度测量。
