The inversion of low resolution infrared scanning equations for a cylindrically symmetrical combustion gas flow is investigated with CO2 (4.3?m) as emitting and absorbing medium. The Lorentz line random band model, exponential-tailed S-1 line trength distribution function and Curtis-Godson approximation are used to express the ransmissivity. An iterative solution of the radiation transfer equation for the temperature profile is established assuming a known absorbing gas concentration distribution. Numerical experiments show the iteration is simple and converges quickly with a high calculation accuracy. The temperature solution is stable to the intensity. Analyses show the influence of intensity error on temperature solution could be expected weaker, if the temperature is lower and the wavenumber used is larger. An approximate formular to calculate the absorbing gas concentration profile from the radiation transfer equation and the transmissivity equation is derived. The inversion of the active infrared scanning equations is formed by combining the concentration formulae and the temperature iteration. Numerical experiments show the inversion is simple and accurate enough for the temperature measurement in engineering applications.

本文以CO_2(4.3μm)为发射与吸收介质,讨论轴对称燃气流低分辨率红外空间扫描方程的反演.使用洛仑茨线的随机谱带模型,指数-倒数线强分布函数和Curtis-Godson近似表示透过率.建立了通过已知吸收气体浓密分布,由辐射传递方程反演温度分布的迭代法.计算试验说明:此迭代法较为简单,收敛迅速,计算精度高.分析说明在较低温度和使用较大波数时,辐射强度误差对温度解的影响变小.推演得到由辐射传递方程和透过率方程求解吸收气体浓度分布的近似公式.此近似公式和温度迭代法组成了主动式红外空间扫描的近似反演.计算试验说明此反演法较为简单,计算精度可满足工程测温的要求.
