摘　　要：在白天进行空间微弱目标光谱探测研究中,除了知道目标的光谱特性外,必须知道天光背景光谱辐射特性。本文以Lowtran软件为基础详细分析了天光背景光谱辐射,在此基础上研制了天空背景测量仪对西部某区域天光背景进行实际测试,给出了该地区天光背景的实验测试结果,为后续光谱探测研究奠定了基础。For the spectral detection of weak targets in space in daytime, the spectral radiation characteristics of not only the target itself, but also the skylight background surrounding the target must be known. In this paper, Lowtran software is adopted to analyze the spectral radiation characteristics of the skylight background, and a skylight background measurement equipment is developed to detect the real spectral radiation characteristic of the skylight background in a certain region in western China. The measurement results may provide useful information for the spectral detection of target in space.（Then the measurement results of it are given, which will lay the foundations of the further research of the spectral detection.）
