When the camera moves at high speed with its carrier

the target image will degrade with radiant blurring from the center to the periphery of image due to such factors as image exposure time

lengthwise relative motion between camera and target

and others.This will reduce the effective field of vision

and affect target detection

recognition and follow-up.An image degradation model has been established and the factors affecting radiant image blurring are analyzed on the basis of motion imaging relations

signal integration mechanism of photo-electronic detectors

investigation on consecutive image degradation models of radiant blurring under high speed lengthwise relative motion of camera platform

analysis of degradation of some specific images

and further analysis of the actual dispersion imaging processes.The restoration approach of radiant blurred image based on recursive algorithm is proposed.The radiant degraded image simulated by computerized method is consistent with the actual image

and the restoration algorthm is verfied through the microcomputer

and experimental results show that the proposed algorithm can mitigate radiant blur of high-speed lengthwise relative movement effectively.
