Atmospheric effects - Some theoretical relations and sample measurements
Abstract
The interaction between radar and the gaseous constituents of the atmosphere is considered. The relations concerning the characteristics of systematic refraction are explored and questions of random scattering are investigated, taking into account weak forward scattering concepts, strong forward (saturation) scattering, and backscatter. A geometrical interpretation of weak scattering is provided and measured values of signal fluctuations are discussed. Attention is given to the amplitude covariance functions for different spectra with experimental data.
