Studies of Enhanced Radar Backscatter

Abstract

Since 1 October 1991, Dr Min-Chang Lee and his students at MIT and Boston Univ., have conducted experimental and theoretical research aimed at investigating ionospheric plasma disturbances which can significantly affect radio wave propagation from satellite communications systems. His efforts have developed a theory to explain reflectivity of radio waves from lightning induced plasmas. In addition, his research has focused on enhanced radar backscatter, source mechanisms for generating symmetric lower hybrid sidebands in the upper ionosphere, and the characteristics of the HF enhanced plasma lines.
