卫星间光通信中多场扫描捕获的仿真优化

在实际的卫星间光通信中，为保证对目标进行确定性捕获，需要采用多场扫描方式。多场扫描范围是多场扫描捕获的关键性参数，需要进行详细的分析。在已经建立的卫星光通信单场捕获模型的基础上，首先对卫星间光通信的多场捕获扫描问题进行了理论分析和模型建立，并以此为依据对多场扫描中的扫描范围的确定进行了研究。分析结果表明，为获得最短的总平均捕获时间需要对扫描范围进行最优化选择。为了便于工程应用，对此问题进行了数值仿真，基于仿真结果给出了多场扫描捕获中最优化扫描范围的确定经验公式。

Simulation and Optimization of Multi-Field Scanning Acquisition in Intersatellite Optical Communications

In the practice intersatellite optical communication (IOC), the method of multi field scanning is needed to capture the goal satellite. And the scanning range is a key parameter of multi field scanning, so the precise study of it is needed. Based on the constructed theoretical single field scanning model, the theoretical analysis has been preceded and a theoretical model of multi raster scanning has been founded too. According to this model, the results of analysis proved that there is an optimization in the selection of scanning range, in order to achieve a shortest acquisition time. And for the convenience in practice, a numerical simulation has been carried on. With the presented simulation results, an experimental formula to choose the optimum scanning range in multi raster scanning has also been proposed.
