摘要 本文从黑体辐射特性出发,根据目标地物、背景大气、传感器的参数等方面研究热红外波段在特定大气模式下的波谱噪声分析,依据目标地物在大气中的自身发射[1]和背景大气发射对比度的相关性及辐射在大气中的传输模型,得出信噪比高的波谱区间。 Starting from the feature of blackbody radiation, article obtained wave spectrum with high SNR through the wave spectrum noise analysis on thermal infrared band on specific atmospheric model according to object on the earth's surface, background atmosphere, parameter of sensor, taking account of the thermal infrared band's self-irradiation in atmosphere and the relativity of the atmospheric radiation.
