摘要
补偿固定噪声的时间漂移是红外焦平面非均匀校正技术中面临的一个重要问题.本文考察了近期提出卡尔曼滤波算法、校正统计算法与代数算法,分析其解决固定噪声随时间漂移的机理,并对算法性能进行综合评价,最后对得出的结论用仿真数据给予验证.
Abstract
Compensating for temporal drift of fixed-pattern noise is an important problem in the techniques for nonuniformity correction of infrared focal plane arrays. Kalman-filtering algorithm, statistical algorithm and algebraic algorithm were examined here. The mechanism for solving temporal drift of the fixed-pattern noise was analyed, and these algorithms performance were comprehensively evaluated. Our conclusions are verified by the simulation data.
