| 摘 要： | 调制传递函数MTF(ModuleTransferFunction)在物理光学理论中 ,是光学系统成像性能的综合评价指标。遥感器MTF的性能变化会导致遥感图像的质量变化 ,遥感图像质量的变化则导致描述遥感图像的参数的变化。文章以CBERS - 1的 0 2星IRMSS遥感器为例 ,在实验室条件下模拟遥感器在轨运行的成像过程并获得图像数据 ,MTF可通过专业仪器直接测量 ,然后再进行MTF与遥感图像参数的相关分析 ,从而确定出与MTF相关性最强的图像参数。文章的相关分析采用SPSS统计分析软件完成

| Abstract: | MTF (Module Transfer Function), in the physical optics theory, is a synthetical evaluation index of imaging performance of optics system. The performance change of MTF of the remote sensor results to the quality change of the remote sensing images, and then results to change of the parameters of remote sensing images.Taking IRMSS of the second satellite of CBERS-as an example, we simulate the change of MTF in the laboratory, obtain the target images with the corresponding MTF and carry out the correlation analysis between MTF and image parameters. Through the analysis results we can find the parameters which have the strongest correlation relation with the MTF. The correlation analysis experiment are implemented by SPSS software. |
