A radio-wave propagation path analysis method and a device thereof are provided. The propagation path analysis method comprises a step of generating a path profile in an analysis section to perform radio-wave propagation path analysis; a step of selecting multiple analysis points to be analyzed on a path of the analysis section; a step of obtaining a Fresnel diameter and clearance at each of the analysis points; a step of determining an obstacle point having the biggest clearance value which exceeds 1 among the analysis points; and a step of modeling the obstacle point to a wedge-shaped obstacle. The present invention minimizes errors between a measured value and a predictive value analyzed with a radio-wave propagation model by modeling the obstacle existing in various shapes to be applied to the radio-wave propagation model.
