白天全天空背景测量与分析

Measurement and Analysis of the All-Sky Background Brightness on Day

开展了白天全天空背景亮度特性数据库研究。利用测量设备进行天空背景全天候测量,对测量数据进行分析与处理,建立了白天天空背景理论模型,提出了基于理论模型的修正完善方法,建立了该位置全天空背景亮度数据库,可给出任意时刻背景亮度值。解决了连续特定位置背景提取难的问题,提高了提取的数量和精度。

The research on database of the all-sky background brightness characteristics on day is developed. The sky back- ground brightness is measured on a place which an electro-optical system is deposited, and the measurement data is analyzed. Based on the theoretical model of the background brightness, a corrected method to consummate the all-sky background brightness is built. Then the database of the sky background brightness is constructed, which can give all-sky background brightness of any time. The shortcoming of background brightness extracting is solved, and the quantity and accuracy of the extracting are improved.
