Abstract:

The objective of the report is the presentation of an analytical- stochastic model capable of predicting relevant statistical scattering features of electromagnetic waves propagating within vegetated environments. The propagation phenomena are described by formulating the scattering associated with ramdom permittivity fluctuations superimposed on a lossy deterministic background slab. The mean backscattered power, its variance and one-point distribution are calculated. The spectral characteristics of clutter from windblown foliage are investigated using two models one presuming the velocity field to constitute a multivariate normal process and another presuming the scatterers motion to be quasi-harmonic over limited time segments.
