摘要：

In response to the current increasing demand for calibration of low-temperature infrared radiation sources with a large dynamic range, this paper studies a calibration method for low-temperature infrared radiation sources with a temperature range of 100-450K. The improvement of the signal-to-noise ratio of the input signal by related detection techniques is analyzed. Developed a radiation calibration device, also called a radiometer, analyzed the calibration and measurement process of the radiometer, and established a corresponding mathematical model. The experimental results show that the minimum radiation intensity that can be measured by the radiometer is 2.47x10(-12) W, and the response rate of the radiometer is 102878.38 V/W. Use the calibrated radiometer to measure the target simulator. The source and contribution of the uncertainty of the radiometer in the measurement process are analyzed.
