The process of the radiation temperature measurement data is to understand the relationship between the spectral em-issivity and the true temperature.If the spectral emissivity model is not in conformity with the actual spectral emissivity model, the large temperature measurement error will be occured.Therefore,it is one of the main problems to be solved in this field in terms of how to reduce the dependence of the spectral emissivity and the true temperature on the measurement model.The paper puts forward an algorithm,which can find out the spectral emissivity and the true temperature without the assumption of the model relationship between the emissivity and wavelength.Through simulation and experiment,the results show that this algo-rithm can be used to solve a relatively reasonable spectral emissivity and meet the requirements of a certain precision of true tem-perature.The algorithm has the features of being simple,reliable,universal,and suitable for spectral measurement of emissivity and the true temperature.%对于辐射测温数据的处理过程实质就是要解决光谱发射率与真温之间的关系.如果假设的光谱发射率模型与实际光谱发射率模型不符,则会造成较大的测温误差.因此,如何减少光谱发射率和真温对测量模型的依赖程度进而使算法具有一定的通用性,是该领域亟待解决的主要问题之一.提出的算法无需预先假定的发射率与波长之间的模型关系即可找出求解出光谱发射率和真温.通过仿真和实验验证结果表明,使用该算法可以求解出一个相对合理的光谱发射率和满足一定精度要求的真温.算法简单、可靠、具有一定的通用性,适合光谱发射率和真温的测量.
