中文摘要：
针对既定目标，采用卫星系统进行协同观测可以最大化卫星系统的整体效能，如何对卫星系统的轨道或载荷参数设计是一个设计空间大、设计变量多的优化问题。对此，采用基于代理模型的仿真优化，通过改进广义模式搜索算法在设计空间中搜索最优解，并以此为核心设计开发卫星系统仿真优化平台。该平台集成问题建模、仿真优化和结果评估显示，为用户提供设计和改进卫星系统方案的方法和依据。采用该平台对卫星系统设计实例进行优化，通过对比发现，平台的优化结果稳定性和优化效率优于STK-Analyzer。
英文摘要：
Satellite system＇s cooperated observation is an effective way to maximize satellite system performance which objects to fixed targets. How to design the orbit or loading parameters of the satellite system is an optimization problem which refers to a huge design space and many design parameters. For this problem,an improved generalized pattern search algorithm, which is based on surrogate model, is put forward to looking for the best sollution in the design space, meanwhile a simulation optimization platform is designed and developed. The platform integrates modeling for problem, simulation optimization and evaluation results to provide users with the method and basis about how to design and improve the satellite system＇s design proposal. Finally, the proposed platform is applied to design a satellite system for a given scenario. Compared to the results got by STK-Analyzer, the proposed platform performs better in stability and optimization effectiveness.
