TLDR
In this article, a review of analytical-numerical approaches for the calculation of single-scattering properties of nonspherical hydrometeors is presented, and the present knowledge of incoherent scattering effects on rain attenuation, cross polarization, and channel transfer characteristics at the microwave and millimeter wave region is also reviewed.Abstract:
Investigation of the scattering properties of hydrometeors, especially those of nonspherical hydrometeors, has become increasingly important in connection with the estimation of depolarization due to hydrometeors in terrestrial and earth-space microwave communication systems. Scattering from nonspherical hydrometeors is also important in remote sensing of precipitation parameters. This paper first reviews various analytical-numerical approaches for the calculation of single-scattering properties of nonspherical hydrometeors. Approaches for the analysis of the practical problems, such as depolarization phenomena and rain scatter interference, are outlined in order to see how the single-scattering calculations are related to these problems. The present knowledge of incoherent scattering effects on rain attenuation, cross polarization, and channel transfer characteristics at the microwave and millimeter wave region is also reviewed.read more

T-Matrix Computations of Light Scattering by Nonspherical Particles: A Review
TL;DR: In this paper, the current status of Waterman's T-matrix approach is reviewed, which is one of the most powerful and widely used tools for accurately computing light scattering by nonspherical particles, both single and composite, based on directly solving Maxwell's equations.

Propagation impairment on Ka-band satcom links in tropical and equatorial regions
TL;DR: In this article, a review of the deficiencies and their likely impact on system performance is presented, highlighting difficulties and encouraging realistic expectations and examining the question of whether costly, application-specific measurement programs might now be avoided by mining increasingly sophisticated national meteorological records.

Uniqueness in the Inversion of Inaccurate Gross Earth Data
George E. Backus,Freeman Gilbert +1 more
TL;DR: In this article, it was shown that a given set G of measured gross Earth data permits such a construction of localized averages, and if so, how to find the shortest length scale over which G gives a local average structure at a particular depth if the variance of the error in computing that local average from G is to be less than a specified amount.
