多星协同观测条件下区域目标的动态划分方法

Dynamic Segmenting Method of Polygon for Remote Sensing Satellites Observing

针对多星对区域目标的协同观测问题建模,提出了基于卫星观测能力的动态划分方法,划分时能够充分利用卫星的每次过境观测机会,依据不同卫星的遥感器幅宽、侧摆能力以及卫星轨道参数特征,以及偏移参数动态划分区域目标,构造多个候选观测场景,特别适用于运动轨迹、工作模式存在差异的多颗卫星联合观测的情况。仿真实验表明,采用本文的划分方法,能够明显提高多星对区域目标协同观测的效率。

The coordinating multi-satellites observing of polygon targets is studied. A novel method of segmenting polygon target is proposed based on the characteristics of sensor and observing target. The factors such as satellite orbit, sensor geometry and slew ability are considered in the method. It can utilize the satellites＇ observing chance, and generate multiple observing scenes for each satellite. It is effective for the polygon observing with multiple satellites, especially for the satellites with different orbit tracks and different observing modes. Experiments show this approach can improve the efficiency of the polygon target observing.
