N2 - Inter-satellite links (ISLs) enable the dense satellite network to remarkably enhance the communication performance of the satellite system. However, the increasing number of LEO satellites and the widespread application of ISLs lead to severe inter-satellite interference (ISLI), restricting communication performance. Therefore, it is essential to study and further restrain the increasingly severe ISLI issue to make full use of the microwave spectrum resources. Meanwhile, considering the importance of satellite network to ground coverage, we construct the problem as a multi-objective optimization problem that maximizes inter satellite signal-to-noise ratio (SINR) and coverage rate. Furthermore, we adopt ϵ-constraint method to convert it into a single-objective optimization problem and propose a low-complexity maximum spatial uniformity constellation design method. Finally, the influencing factors of ISLI are analyzed through simulation, and the feasibility and effectiveness of the proposed method are verified.
