中文摘要: 通过空间结构函数分析法,分析了风云二号扫描辐射计可见光通道的噪声。计算结果表明,风云二号扫描辐射计可见光4个通道的噪声水平不完全一样,其中通道1的等效噪声计数值最大,为0.51,其它3个通道的等效噪声计数值为0.42~0.45。

Abstract:In order to analyze the noise level of FY2 VISSR VIS channels using the space areas data on FY2 VIS full Earth disk imagery,space structure function analysis was used. The results show that the noise level of FY2 VISSR VIS channels are not the same,the equivalent noise level of CH1 is 0.51,and the equivalent noise level of the other channels are from 0.42 to 0.45.
