摘要
随着导弹技术的发展和红外技术的进步,红外成像制导技术越来越受到研究人员的重视.红外微弱目标的检测技术是红外成像系统中的核心技术之一.低信噪比条件下的微弱目标检测与跟踪问题也一直是近些年来国内外学者研究的一个热门课题.由于红外图像本身起伏背景复杂而微弱且又只占一个或几个像元,往往淹没在背景中,造成信噪比太低而无法进行检测.为此围绕着低信噪比条件下的微弱目标检测与跟踪问题,通过对目标的观测模型分析,总结出外微弱运动目标检测与跟踪系统的通用原理框图.
With the development of missilery and technique, researchers are paying more and more attention to infrared imaging guidance technique. The technique of dim infrared target detection is one of the key technologies in the system of infrared image information. The effective detection for dim targets in low SNR images has been becoming a hot research field these years. Because the target only occupies one pixel, its SNR is low and the target almost be submerged by noise, these all bring huge difficultv to detection. Around the problem of the effective detection for dim targets in low SNR images, this article introduces a universal diagram that the technique of dim infrared target detection through analysis of the observatory model.
