| Abstract: | 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. |
