Abstract :
In this paper, a theoretical platform for analysis of radar cross section of a finite stratified dielectric cylinder, representing a tree trunk, above a smooth distributed rough surface, representing the terrain, using reaction theorem is demonstrated. In this analysis, the second order interaction between tree and terrain (multiple scattering term) is included in the modeling platform to enhance the accuracy of the forward analytical model. An extensive set of Monte Carlo simulations have been utilized to calculate and validate the average scattered power (coherent and incoherent terms) against analytical model.
