| 在低轨电子侦察、遥感卫星领域，针对非连续覆盖条件下的星座优化设计问题，提出了一种间隔重访的低轨星座设计方法。通过改进极轨覆盖带设计方法，将对地覆盖区域等效为矩形；以对地目标的平均重访间隔时间为输入，从同轨卫星间和相邻轨道面间两方面分析,得到近似最优的星座参数。通过STK仿真验证，设计的星座可满足重访间隔时间要求。 |

| Abstract: |
| For the problem of designing optimal constellation under the condition of discontinuous coverage,a method of designing low Earth orbit(LEO) constellation for interval revisit is proposed in the area of LEO electronic reconnaissance and remote sensing satellites.By improving the method of Street of Coverage(SOC) for polar orbit satellite constellations,the area of coverage to the Earth is equivalent to a rectangle.According to the average revisit interval of the constellation to the ground target，the revisit interval among satellites in the same orbit and between orbital planes is analyzed,and approximate optimal parameters of constellation are obtained.The STK simulation result shows that the designed LEO satellite constellation can meet the requirements of revisit interval. |
