title: [Studies of the thermal radiation multi-angle polarization properties of snow].
abstract: This paper, catering to the need of the study of remote sensing for thermal radiation polarization properties of ground features, detects the thermal radiation multi-angle polarization properties of snow, and makes analysis of effects of four factors, i. e. detecting zenith angle, detecting azimuth angle, bands and polarizing angle, on the thermal radiation properties of snow. The results show that the radiance and brightness temperature of snow increases with the detecting zenith angle. When the detecting zenith angle is greater than 30 degrees, the growth accelerated, and the effect of detecting zenith angle on the brightness temperature of snow is more significant than that of the radiance; the changes in detecting azimuth angle have some effect on the radiance and brightness temperature of snow, and have much influence on the brightness temperature than that of the radiance; the radiance and brightness temperature of snow is significantly affected by the changes in bands, and the effect on the radiance is more significant; the changes in polarizing angle have some effect on the radiance and brightness temperature of the snow, and have much influence on its brightness temperature. The results of the study provide new ideas and methods for the application of remote sensing technology to carrying out the thermal infrared quantitative study of snow, and have important theoretical significance and potential applications.
