摘　　要：为了将非致冷红外焦平面阵列应用于不同环境的辐射定量测量,设计了一种基于标准辐射源的定标试验方法,并在理论分析的基础上,根据定标试验数据,提出了一种考虑探测器工作温度效应的非致冷红外焦平面阵列辐射定标模型。试验数据分析表明,非致冷红外焦平面阵列响应动态范围大、线性度好,探测器工作温度效应可作线性化处理,辐射定标模型反演标准偏差为0.72 w/(m2.sr)。In order to measure radiance with Uncooled InfraRed Focal Plane Array （UIRFPA） under different conditions, a calibration experiment method based on the standard radiant source was designed, and a radiometric calibration model which involved detector temperature effect was proposed according to the calibration test data and theoretical analysis. The experiment results show that the UIRFPA has good response linearity, wide dynamic range, that the detector temperature effect is linear, and that the retrieval standard deviation of the radiometric calibration model is 0.72w/（m^2·sr）.
