Numerical simulation of polarization characteristics of an echo signal in the process of ground-based cloud sensing in the terahertz range


Results of numerical statistical simulation of an experiment on ground-based sensing of the cloud layer by linearly polarized terahertz range radiation at several wavelengths from the transmission windows of the atmosphere are presented. The models of the scattering layer involve liquid droplet size distribution functions pooled by results of long-term field experiments in middle latitudes of the Earth, as well as distribution functions obtained in flight measurements near the coast of Great Britain. The models of the scattering medium take into account the vertical stratification of water vapor in the atmosphere and the difference in the microstructure of the cloud layer near its top and bottom.
