| 摘 要： | This paper addresses the estimation of adjacency effect of CBERS-2 image. The adjacency effect influences the digital number (DN) value of a pixel by adding surrounding scattering signals and path scattering signals. Based on the theory of radiation transfer model, a procedure is designed to measure the reflectance from the surface target materials and the materials in a box, which is 1.5 m above the surface to avoid upwelling reflectance. The results show that the adjacency effect varies from visible, near infrared and becomes steady within short infrared wavelength region; the adjacency effect weakens with the increase of distance between testing sites. The adjacency effect of CBERS-2 image is corrected and the quality of the resulting image is improved.
