Hello,
assuming the propagation of a purely vertical polarised FMCW radar uses the phased.TwoRayChannel. Is it correct to calculate the ground reflection coefficient used by the phased.TwoRayChannel property: GroundReflectionCoefficient as
Gamma_v = epsilon_r * sind(tgt_ang) - sqrt(epsilon_r - cosd(tgt_ang).^2)./ ... (epsilon_r * sind(tgt_ang)+ sqrt(epsilon_r - cosd(tgt_ang).^2));
where tgt_ang reflects the grazing angle (90°-angle of incidence) calculated by Matlabs rangeangle function? Since the E-Fields are vertically polarized only I do not want to start using polarization throughout my simulation.
Thank you! Dominic

This is a valid equation and it could work. Since this is for parallel incidence, i.e., the signal is in the incidence plane, you want to make sure that your signal satisfy that requirement.
