【摘要】 文章主要对凝视红外焦平面热成像系统的噪声进行研究。在与第一代热成像系统工作特点相比较的基础上，详细分析了第二代凝视成像系统的主要噪声。然后，介绍了一种先进的噪声分析模型———三维噪声模型，使得分析更为简化，并结合这一模型对凝视成像系统的主要噪声进行分析，为提高系统性能提供理论依据。更多还原

【Abstract】 In this paper, the noise of staring IR focal plane array thermal imaging system is discussed. The main noise of the second generation thermal imaging system which is compared with the first generation thermal imaging system in the former part of this paper is analyzed in detail. Then, an advanced noise analysis model——3\|D noise model is introduced, which makes the analysis of noise easier. The main noise proposed above is discussed by combining with such a 3\|D noise model, which provides a theoretical basis for improving the performance of a thermal imaging system. \;更多还原
