种针对中等规模超宽幅遥感星座的构型优化 设计方法

To address the main shortcomings of large revisit intervals and excessive ineffective revisits in medium-scale ultra-wide-swath remote sensing satellite constellations utilizing the Walker constellation configuration，a satellite constellation configuration design method based on the optimized combination of multiple Walker constellations is proposed. A preprocessing strategy is employed to decompose the medium-scale satellite constellation into multiple small Walker constellations with different configurations. Satellite constellation characteristics are extracted，and combined design variables are incorporated into heuristic algorithms for optimized design，ultimately delivering a composite Walker constellation configuration. Following the presentation of the optimization design process，the optimization value of medium-scale remote sensing satellite constellation configurations and the variation patterns among different variables are discussed. Simulation results are provided to validate the proposed approach. It is demonstrated by the simulations that significant improvements in revisit performance metrics and constellation robustness are achieved by constellations designed using this algorithm compared to traditional Walker constellations.
