目标光学有效反射面积计算模型研究

随着对飞行器测控要求的提高，测控应用中一些重要参数的定性估计或概略计算模型已不能满足要求。改进飞行器测控工作中目标的“光学有效反射面积”参数计算模型，根据目标有效反射面积的定义建立面元模型，在此基础上建立若干典型形状目标的计算模型以及日照约束模型，并对所建立的新模型进行了实例计算和分析，计算结果和试验数据一致。

Research on Computing Model of Target Optical Effective Reflective Area

With the increasing requirements on spacecraft TT&C, qualitative estimation and rough computing model for some important parameters no longer meet demand. This paper introduces a parameter computation model for target effective optical reflective area verification of the effectiveness of the model. The process is reformulated in three steps. First, a facet model is established by the parameter's definition. Second, target's shape model such as the column, the taper, etc. is explained quantitatively. A new simple sun-to-spacecraft sunlight model is also established. Finally, the proposed new computing model is verified and real data computation results and analysis are presented.
