基于系统非线性的红外焦平面非均匀性校正

采用系统非线性描述和分析方法,从基于红外参考辐射源的校正算法原理入手,提出了一种新的红外焦平面非均匀性校正方法.该算法将每个探测器单元视为一个非线性系统,因此,该算法原理既对基于红外参考辐射源的非均匀性校正算法成立,对基于场景的校正算法在一定条件下也有效,能够适应非均匀性随时间和环境改变而发生缓慢变化的情形,是一种自适应算法.

NONUNIFORMITY CORRECTION FOR IRFPA BASED ON SYSTEMIC NON-LINEARITY

Using systemic non linearity statement and analysis,a new IRFPA nonuniformities correction algorithm is developed from the principle of correction algorithms based on IR reference emitter.Each detector unit is treated as a non linear system according to the algorithm,from which the principle is valid for nonuniformities correction algorithms based either on scene moving analysis with certain conditions or on IR reference emitter,it can adapt to the nonuniformities change slowly with time and with external conditions and is really a adaptive algorithm.
