太阳直射及太阳翼对星载微波辐射计影响分析
|
摘要
提出一种星载微波辐射计在轨运行时,计算太阳直射及卫星太阳翼自身辐射对其亮温测量影响的定量分析方法。依据太阳翼辐射发射率数据和星载微波辐射计测量原理,对太阳直射和太阳翼自身辐射进入星载微波辐射计天线波束内对其造成的亮温测量误差进行了理论分析,分析结果可以为卫星在轨偏航策略和整星结构布局的设计提供理论依据。如果在轨偏航策略和整星结构布局设计无法保证星载微波辐射计远离太阳入射方向或者太阳翼自身辐射影响,则可以按此分析方法在轨实时计算并剔除太阳直射及卫星太阳翼自身辐射给星载微波辐射计带来的亮温测量误差。
Based on microwave radiance data of sun wing panels,measurement error analysis of sun and sun wing panels is given.And it can be used as a theory basis of satellite yaw control strategy and configuration and Layout design.If the microwave radiometer cannot be far away from sun or sun wing panels by configuration and Layout design,the method can also be used to remove the error for brightness temperature brought by sun and sun wing panels in-orbit.
