| The calibration of infrared staring imaging systems is to acquire the accurate quantitative relation between it's digital output and radiance energy of objects. This paper establish the mathematics formula of radiometric calibration of infrared staring imaging systems by an advanced weighting function based on the linearity response of infrared focal plane arrays sensor of infrared camera, and establish the mathematics formula of non-linearity based on the fact that the response of the IRFPA is non-linearity.In this dissertation, the radiometric calibration of camera was performed, and researched the influence of non-uniformity of sensors response to calibration, calibration precision was improved by reducing the influence of random noise to calibration by processing the data of calibration by using Wiener filtration. The radiometric calibration coefficients are determined by measuring the output data of camera and the temperature of blackbody.
