To correct the nonuniformity of long-wave infrareddetectors,a nonuniformity correction method based on statistical consistency of adjacent pixels is proposed.First,the model of radiance nonuniformity is introduced.Then,the ratio between adjacent pixels is estimated with a mean operator,and the correction coefficients are calculated iteratively.Finally,aprinciple prototype is set up to grab different scenes.Experimental results demonstrate that the proposed method can decrease the roughness of the corrected ...

0引言长波红外探测器常应用于红外搜索与跟踪系统(Infrared Search and Track,IRST)和红外导引头系统中.与雷达系统相比,IRST系统具有无源、不受电磁干扰和测向精度高等优点,是雷达预警系统的有效补充.但由于读出电路和每个像元的辐射响应的差异,红外探测器常受严重的非均匀性?
