| Abstract:The ground-based infrared imaging system is one of the important imaging devices for target tracking and recording in real time. The ground-based long-wave infrared imaging system equipped with a high-performance infrared radiation calibration system can realize high-precision radiation characteristics measurement at room temperature. By establishing the model of a cooling infrared radiation characteristic measurement system, high-precision measurement of a target is implemented by a long-wave infrared radiation measurement system in the long-wave band from 7.7 μm to 9.3 μm. The experimental results show that the radiation measurement accuracy is 16.81 percent. It can meet the high-precision radiation measurement requirements of a shooting range. |
