对超地平覆盖飞行器的概念及特性进行了简要的描述,以该类飞行器中的通用航空飞行器(CAV)为例,对该类型飞行器组网星座的优化设计进行了研究.首先基于单个CAV对地覆盖区域的分析,提出了一种几何意义更加清晰和简单的CAV再入对地覆盖区域的分析方法;其次通过提出等效的CAV星座覆盖性能指标-平均轨道响应时间,建立了CAV组网星座优化设计的数学模型;最后通过采用遗传算法对CAV组网星座进行了优化设计.通过分析优化设计的结果,说明了这种设计方案的有效性.
A brief description of the concepts and characteristics of the over-the-horizon coverage aircraft is given, and the optimization design of the constellation of this type of aircraft network is studied by taking this general aviation vehicle (CAV) as an example.Firstly, The analysis of the coverage area, a more clear and simple geometric meaning of the CAV re-entry coverage of the ground analysis method; followed by the proposed CAV constellation coverage performance index - the average orbital response time, established CAV constellation Optimize the design of the mathematical model; Finally, through the use of genetic algorithms to CAV constellation of network design optimization.Through the analysis of the results of the optimal design, illustrates the effectiveness of this design.
