RAYLEIGH SCATTERING FROM LEAVES,

Abstract

A Rayleigh region leaf model, consisting of a layer of uniformly distributed and randomly oriented leaves, is developed as a first approximation of a jungle environment. Such a model is appropriate for clutter calculations and for estimating the constitutive parameters of the medium. In this report, emphasis is focused on the latter application. Explicit expressions for the scattered field and the absorption and scattering cross sections of a single leaf are developed. From these results, the effective dielectric constant and conductivity of a layer of uniformly distributed and randomly oriented leaves are derived. Numerical calculations of these parameters for a frequency range from 30 to 300 MHz, leaf water contents from 10 to 50 per cent, and leaf volume concentrations from 0.03 to 0.1 per cent are made.
