Abstract

Abstract:

Regarding the existing deficiencies in the analysis and simulation of degradation effects of the simulated optical images of space targets in extreme space environments, this paper analyzes the imaging characteristics in the extreme space environment and the degradation effects of space target optical imaging. Gaussian filtering is employed to calculate and simulate the imaging blurring degradation effects caused by atmospheric scattering and point spread effects. A simulation calculation process method for the halo artifact effect based on the number of overexposed pixels in the neighborhood is designed. Moreover, the simulation results of the imaging degradation effects under different conditions are comparatively analyzed. The simulation method of the degradation effects of space target optical imaging proposed in this paper can provide technical support and an effective approach for the calculation and generation of high-fidelity image data in the extreme space environment.

Key words: space target, imaging simulation, degradation effect, halo artifact
