The invention discloses an on-
orbit spectrum precision test method and equipment for an
ultraviolet hyperspectral remote sensor, and the method comprises the steps: selecting a high-resolution reference solar spectrum higher than the
spectral resolution of the
ultraviolet hyperspectral remote sensor, and calculating a reference standard solar spectrum according to the high-resolution reference solar spectrum; establishing a reference
wavelength library according to the reference standard solar spectrum of the
ultraviolet band, and selecting a standard absorption line meeting conditions as a reference
wavelength; screening an absorption peak center position of the observation spectrum, finding an absorption peak center closest to the reference
wavelength in combination with the reference wavelength
library, and constructing a peak searching
database of the absorption peak center of the
discrete spectrum; and calculating a difference value between the central wavelength calculated according to the peak searching
database and the corresponding reference wavelength to obtain the spectrum calibration precision of the ultraviolet hyperspectral remote sensor. According to the method, the precision difference of the spatial dimension can be identified, the distribution of the overall
system deviation is quantified, and reliable support is provided for on-
orbit precision
verification and performance optimization of the ultraviolet hyperspectral remote sensor.
