The article describes the basic working principle and application characteristics of TDI-CCD devices  analyses the composition of TDI-CCD imaging noise  and propose a new method to analyze TDI-CCD imaging noise with statistical probability distribution. In order to estimate the distribution of gray values affect by noise we introduced the concept of skewness and kurtosis. We design an experiment using constant illumination light source  take image with TDI-CCD working at different stage such as stage 16  stage 32  stage 48  stage 64 and stage 96  analyse the characteristics of image noise with the method we proposed  experimental results show that the gray values approximately meet normal distribution in large sample cases. 2011 SPIE.   Hyperspectral remote sensing monitoring of grassland degradation 期刊论文  iSwitch采集 Spectroscopy and spectral analysis, 2010, 卷号: 30, 期号: 10, 页码: 2734-2738 作者:  Wang Huan-jiong;  Fan Wen-jie;  Cui Yao-kui;  Zhou Lei;  Yan Bin-yan 收藏  |  浏览/下载：39/0  |  提交时间：2019/05/10 Hyperspectral  Grassland degradation  Spectral characteristics  Mixed spectra unmixing   Hyperspectral Remote Sensing Monitoring of Grassland Degradation SCI/SSCI论文  OAI收割 2010 Wang H.
