【摘要】：随着无人机技术在各个领域崭露头角,无人机目标在红外波段的辐射特性成为人们非常关注的问题。本文首先对中、长波红外探测器进行辐射定标,针对飞行中的无人机目标的辐射特性进行测量,对飞行状态下的无人机目标的温度进行了反演,分别采用了单波段、双波段比色法、基于黑体校正的双波段法进行探测,结合实测数据对上述各种方法进行了分析对比,对测量结果进行了精度分析并给出误差源。结果表明,实验中的无人机中波辐射强度约为0.04W/sr、长波辐射强度在0.5 W/sr左右,采用基于黑体校正的双波段测量方法能极大提高无人机目标温度反演的精度。反演温度的绝对误差降低至2 K,相对误差仅为0.5%左右。
[Abstract]:With the emergence of UAV technology in various fields, the radiation characteristics of UAV targets in infrared band have become a very concerned issue. In this paper, the radiation calibration of medium and long wave infrared detector is carried out, and the radiation characteristics of UAV target in flight are measured, and the temperature of UAV target in flight state is inversed, and the single band is adopted respectively. The dual-band colorimetric method is used to detect the method based on blackbody correction. Combined with the measured data, the above methods are analyzed and compared, and the accuracy of the measurement results is analyzed and the error source is given. The results show that the medium wave radiation intensity of UAV is about 0.04W and the long wave radiation intensity is about 0.5W. the dual-band measurement method based on blackbody correction can greatly improve the accuracy of UAV target temperature inversion. The absolute error of inversion temperature is reduced to 2 K, and the relative error is only about 0.5%.
