A Review of Microwave Cross Polarization in Sand and Dust Storms

摘要

This paper presents a review of cross polarization in sand and dust storms (SDS). Relevant past works have been identified and their contributions to microwave cross polarization have been highlighted. Attention was given to semi-empirical models since they are used most readily for statistical predictions in design applications. The cross polarization mechanisms and parameters are also presented as well as a discussion about the advantages and the constraints of some of the models and their methodologies. Modified cross polarization discrimination (XPD) models for both terrestrial and slant links are proposed. Besides, the gaps in knowledge are established and the outlook of this topic in future is also suggested.
