Taking the hyperspectral resolution of Spatial Heterodyne Spectrometer (SHS) as an example, and extracting from the characteristics of the ground surface interferometric data with SHS, this paper proposed a method to match and correct the pointing error of SHS. It used the feature of large area uniform landform and abrupt change of the surface reflectance in coastline area of the high spatial resolution remote sensing image This method realized the matching application between non-coaxial imaging remote sensing equipment and non-imaging remote sensing equipment. The SHS was used to perform ground-based testing experiment on the results of interferometric data at several earth observation points and high spatial resolution image data in the same latitude and longitude region. The results of the calibration correction were compared with their nominal values. The error ranges from -3 % to 5%. The results show that the proposed method can be used as a reference for matching application between non-coaxial imaging remote sensing equipment and non-imaging remote sensing equipment on board the satellite.
