A Novel Testing Method for the Radiometric Responsivity of Satellite Cameras

Abstract

To solve the problems of harsh test conditions and the complex process of visible imaging satellite cameras, a testing method suitable for conducting at the launch site was proposed to address the limitations of the original test design. The method is highly efficient and accurate enough in evaluating the radiometric responsivity of satellite cameras, with the advantages of fully controllable test conditions, convenience, and high accuracy. Using a certain type of optical satellite as an example, the proposed method is used to test the radiometric responsivity of satellite cameras and compare the results with those obtained by the traditional integrating sphere testing method to verify the validity and reliability of the testing method.
