采用云量仪提高光电望远镜观测效率的探索

Exploration for Improving the Efficiency of Photoelectric Telescope with the Cloud Imager

光电望远镜按编目次序对空间碎片进行跟踪,对于有云层分布的夜空,不能根据云量分布情况实时调整观测次序,造成望远镜资源浪费,影响探测目标数量.云量仪用于实时采集全天空的红外云量图像,测定云量分布与定位的同时,可以对望远镜的观测调度策略进行优化.实验测试表明云量仪优化的观测调度策略有效可行,能够充分利用现有资源,在多云条件下使望远镜实现见缝插针式的工作,显著提高观测设备效率.

The photoelectric telescope tracks space debris with the catalog. But for the night sky under cloud cover, it can not adjust the observation sequence according to the real-time cloud distribution, which results in a waste of telescope resources, and a decrease in the quantity of detected objects. The cloud imager is used for the real-time acquisition of all-sky infrared cloud image, and the observational scheduling strategy of telescope is optimized by determining the clouds＇ distribution and position. Optimized scheduling strategy is benefit for the telescope to shoot through the smallest breaks under cloud cover, allowing the observations to be carried out in the weather conditions previously thought to be too bad. Experimental tests show that the optimized scheduling strategy is feasible. It can make full use of existing resources, and significantly improve the efficiency of observation equipment.
