摘要

研究了卫星上指向太阳安装的宽视场绝对辐射计在轨飞行中

太阳越顶扫过其视场期间接收的辐射功率随时间的变化

给出了绝对辐射计接收这种时变辐射功率的情况下腔温响应函数.只要绝对辐射计的视场宽到一定程度(10°)

太阳越过视场的这段时间太阳辐照基本上是恒定的

辐射计的腔温响应也能达到平衡

根据这一腔温响应的平衡点关闭快门进行电功率定标就能获得太阳辐照度值.并将这种测量方法用于神舟3号飞船上用3台15°视场太阳辐照绝对辐射计(SIARs)

测量了太阳辐照度.实验结果表明:所测数据与同期卫星上获得的数据基本一致

这也表明了本方法的可行性.

Abstract

The change of the sun incidence power with time during the sun flies over the view field of the absolute radiometer mounted on spacecraft

and the temperature response function under the change were given. While the view field is 10?

the solar irradiance is invariable

and the temperature response of the cavity of absolute radiometer reaches balance. And the solar irradiance value can be observed by closing the shutter at the balance point and electric calibrating. The solar irradiance was measured in this way by the solar constant monitor mounted on Shenzhou-3 spacecraft

which is consisted of three Solar Irradiance Absolute Radiometers(SIARs)with 15? view field. The result is: the data correspond well with that measured on other satellite in the same term. And the result also indicates that the method is feasible.
