Paper Abstract

In order to ensure the radiometric imaging quality for the space-borne camera with super-wide field of view, we put forward a new method, with which the apparent spectral radiance for any field of view can be precisely calculated. Firstly, building the imaging model for the space-borne camera, and the parameters of the orbits and attitudes of satellite, the look direction for the given field of view, the characteristics of different ground objects, the state of the atmosphere, et al.. Secondly, calculating the geometrical observation parameters for the given look direction of the space-borne camera. Finally, using the radiative transfer model to calculate the value of the apparent spectral radiance. Then, we use this method to calculate the apparent spectral radiance for the space-borne camera with the FOV of 75°based on freeform mirror on a small remote sensing satellite. And the result shows that the relative non-consistency of the apparent spectral radiance can be 25.3%, when the satellite takes the imaging of the area of North Atlantic. And we should greatly consider the characteristic of the radiometric imaging quality for the space-borne camera with super-wide field of view.
