卫星可见光遥感图像异常原因分析方法初探

随着中国高分辨率可见光遥感卫星数量日益增多，在轨卫星的图像品质和异常原因分析将成为今后一段时间相关研制人员关注的重点。文章列举了在轨可见光卫星的成像异常现象，分别对地面分辨率、对比度、信噪比和几何形变未能达标的原因进行了初步分析，提出了问题定位的初步方法。

Problem Location Method Research for Satellite Panchromatic Imaging

As more and more high resolution panchromatic imaging satellites were sent into space,image quality and imaging problem analysis would attract the engineers attention for a long time.The paper cited several abnormal imaging phenomenon,analyzed the causes of failure factors of GRD,contrast,SNR,and geometric deformation.Some primary methods were proposed for imaging problem location.
