本文从理论上分析了红外线性阵列(简称线列)温度非均匀性的产生及其所对应的非线性稳态温度场方程和边界条件。指出温度的非均匀性将导致各探测单元间的D~*(λ、T)不同,D~*(λ、T)绝对值差异产生的非均匀性可以通过对单元器件放大倍数的数值修正来进行补偿,而D~*(λ、T)随λ、T分布不同产生的非均匀性将无法用单纯数值方法进行补偿,它将在输出图象上产生一个与温度非均匀性分布相关的空间色噪声。 In this paper, the generation of temperature inhomogeneity of infrared linear array (line array) and its corresponding nonlinear steady-state temperature field equations and boundary conditions are theoretically analyzed. It is pointed out that the nonuniformity of temperature will lead to different D ~ * (λ, T) between detection units and the nonuniformity of absolute value of D ~ * (λ, T) can be corrected by numerical correction of unit magnification , And the nonuniformity of D ~ * (λ, T) with different λ, T distributions will not be compensated by a simple numerical method, which will create a space on the output image that is related to the distribution of temperature inhomogeneities Colored noise.
