| 摘 要： | 面向海洋观测的成像卫星是一种轨道较高的可见光对地观测卫星，主要用于探测海上船舶活动以及监测海洋环境参数等。对地观测卫星任务规划问题是一个复杂的组合优化问题，通过分析面向海洋观测的成像卫星工作特点及约束条件，建立了一种考虑多数传模式共存的数学模型，提出了一种基于最大收益损失比的卫星任务规划算法。试验结果表明该方法能够有效解决面向海洋观测的成像卫星任务规划问题。

| Abstract: | Image satellite oriented ocean survey (ISOS) is a type of earth observation satellites(EOSs) in high orbit. The scheduling of EOS is a complex combinatorial optimization. A mathematical model with multiform data transmission mode coexistence was proposed by analyzing the constraints and characteristics of ISOS. A scheduling algorithm for ISOS based on the maximal ratio of gain and loss was presented. The experimental results show that the proposed model and algorithm are effective in solving the scheduling problem of ISOS. |
