本文对红外相机进行辐射定标，研究了探测器响应的非均匀性对定标的影响，并通过采用wiener滤波技术对所采集的数据进行滤波处理，减小随机噪声对定标的影响，提高了定标的精度，最后通过测量黑体温度和相机输出数据完成红外相机辐射定标。 - The approach is that we first calibrate the filter radiometer with cryogenic radiometer and measurement equipment of relative spectral responsivity and then calculate the absolute spectral responsivity . because the drift in blackbody temperature directly influnces measurement accuracy , so we adopt a feedback system to stabilize blackbody temperature through controlling the current of blackbody that improves measurement accuracy greatly
