A ray tracing theory incorporating the ray intensity calculation has recently been developed at DREV. This report studies the applicability of this new ray theory to radar propagation. Using this theory, we tried to characterize the anomalous behavior of the propagation due to the refractivity of the troposphere. This report summarizes the ray theory and the validity of this approach for the study of radar propagation. A computer model has been developed to calculate ray trajectories and intensities. Considering the case of a simple surface duct, the results have shown that the intensity computation is an effective and powerful way of detecting and locating in space such singular propagation phenomena as caustics and radio holes.
