以区域侦察为背景,基于遗传算法提出了一个侦察卫星星座设计方法。研究了通过遗传算法模型优化设计侦察卫星轨道倾角、右升交点角以及平近点角等轨道参数的方法。分析了轨道高度与最大访问间隔时间之间的关系。基于7种不同轨道高度对有3颗低轨道卫星的侦察卫星星座进行了优化仿真。结果表明,优化后的星座不仅在指定目标区域具有优异的最大访问间隔时间性能,而且具有一定的全球侦察能力。
Based on the regional reconnaissance, a reconnaissance satellite constellation design method is proposed based on genetic algorithm. The method of optimizing orbital parameters of reconnaissance satellites, such as orbit, right ascendant point and plane near point angle, is studied through genetic algorithm model. The relationship between the orbital height and the maximum access interval time was analyzed. The reconnaissance satellite constellation with three low-orbit satellites was optimized based on seven different orbital altitudes. The results show that the optimized constellation not only has excellent maximum inter-access time performance in the designated target area, but also has certain global reconnaissance capability.
