Research on Image Restoration of Roll-Swing Imaging Seeker

摘要：

To achieve a correct image receiving for Roll-Swing imaging seeker, the mechanism and imaging process is analyzed. The causes of image rotation are discussed. The influence of the frame encoders precision on imaging de-rotation quality is analyzed. The RollSwing imaging seeker is designed for high-speed aerocraft, thus the received images are greatly degraded due to atmospheric turbulence. A new method of image restoration is proposed for turbulencedegraded images in this paper. The method is to get point spread function (PSF) based on the estimation of optical transfer function (OTF) according to the optical system design simulation. Finally, to obtain the restored image, constrained least squares filtering is used with the known PSF. The experiment results indicate that the new restoration method has a favorable effect to satisfy requirement of the automatic target recognition.
