摘　　要：简述了在不同航天任务上测量太阳总辐射的各种辐射计,以及这些辐射计的结构、仪器特性、原理和运行等。这些空间辐射计大多数采用电标定的原理,以腔体探测器作为感知太阳总辐射的传感器。讨论了空间辐射计寻日方式对太阳总辐射测量精度的影响。最后,结合以往宇航任务中太阳总辐射测量的历史和经验,简述了高精度测量太阳总辐射空间辐射计的发展趋势。Several kinds of radiometers on different spacecrafts for Total Solar Irradiance （TSI） measurements are briefly described in this paper, and their structures, instrument characteristics, principles, and operation are introduced. It shows that the TSIs for most of spaceborne radiometers are measured using the principle of electrical calibration, and the cavity detectors are taken as sensors for the TSI. The influence of sun-pointing manner on measurement accuracy of TSI is also discussed for the spaeeborne radiometers. Finally, based on the history and experiences of past space missions, the future development of spaceborne radiometers with high accuracy for measuring TSI is discussed.
