Abstract

The performance of a remote sensing imaging system is often degraded by wave-front aberrations that introduced by different sources such as the atmospheric disturbance and the aberrations of the optical system. A new remote sensing imaging system based on phase diversity (PD) method which does not need a priori information and has simple configuration and high reliability, is designed in this paper. The process of image reconstruction based on PD method is simulated according to the characteristics of space and aerial remote sensing imaging system. The index of energy gradient function of the image obtained by using PD method is improved greatly. The simulation results prove that PD method has special potential to improve the image quality in remote sensing imaging system.
