Abstract: Due to the urgent demands arising in civil aviation, the radar detection of wake vortics is becoming an increasingly important issue in the field of radar technology. As a special time-varied, non-uniform, distributed, weak-scattering medium, not only does the study of the scattering characteristics of wake vortices deserve much attention in theoretical aspect, but also it plays an important role in the development of corresponding radar detection technology. Currently, there are generally three approaches to measure the scattering capability of wake vortices: volume reflectivity, line reflectivity and radar cross section (RCS). However, the physical essences of these approaches, as well as their relationships and transformations, remain uninvestigated. This paper discusses the above-mentioned issues, and the findings could provide helps to further studies of wake vortices scattering characteristics and their applications. ©2012 by Editorial Department of Chinese Journal of Radio Science.
