摘要  介绍了红外焦平面阵列所存在的非均匀性问题对系统性能的影响,分析了非均匀性校正通常所采用的标定法的缺陷,以及一种常用的自适应算法在实施中的一些问题,探索了各自的实用性和局限性以及某些可能的改进。 The nonuniformity of infrared focal plane array(IRFPA) and its influences on infared systems are introduced. The limitations of current calibration nonuniformity correction(NUC) algorithms and some problems of a popular adaptive NUC method are analyzed. The practicability, limitations and some available improvements are investigated.
