微波辐射计的长期稳定性，是影响最小可检测信号的主要因素．研究出数字增益补偿与实时定标两种新型微波辐射计．能完全消除系统增益波动的影响．有极好的长期稳定性．实时定标型还能消除系统噪声的波动，完成实时定标在0．6S时间常数下最小可检测信号分别达到0．13和0．19K，达到国内外先进指标．在实际中已得到应用．
The long-term stability of the microwave radiometer is the main factor that affects the smallest detectable signal. Developed two new types of microwave radiometers, digital gain compensation and real-time calibration. Can completely eliminate the impact of system gain fluctuations. Excellent long-term stability. Real-time calibration can also eliminate the system noise fluctuations, the completion of real-time calibration at 0.6S time constant minimum detectable signals were 0.13 and 0.19K, reaching advanced indicators at home and abroad. In practice has been applied.
