摘　　要：针对多颗成像侦察卫星对区域目标进行观测的摆角方案优化选择问题,利用先预处理再建模的思路实现优化建模。在模型求解阶段,利用贪婪算法的思想,设计相应的贪婪规则实现模型的优化求解。实例证明本方法可以得到较好的摆角方案。This paper presents an elevations selection approach of area target surveillance task using multi-satellites. The approach included two stages：pretreatment and optimization. In the pretreatment stage,STK was applied to solve the difficult problem of computing access time,in the optimization stage, models and solving method based on Greedy Algorithm was presented. Finally,a scenario instance proved the validity of the method.
