Abstract

A diffuse target illuminated by the sun radiation is used for on-board calibration of a new stereo-spectral-imaging system ARGUS developed in the frame of the International project for MARS 94/96 missions. The target manufacturing technique is described. The experimental procedure used for getting the spectral and angular responses of target reflectivity is presented. The diffuse target was tested for the spectral properties at angle illumination -70 degree(s) (relative to the normal of the target) and angle of viewing +20 degree(s). A brief description of the setup for measurements of the spectral and angular responses of the target reflectivity is given. Results of the diffuse target calibration in the spectral range from 320 nm to 5200 nm are presented.
