Prediction System About Path Loss Of Radio Propagation Based On Gis

Prediction of the field strength is important in radio wave propagation in radio and television industry. Affected by the complex terrain on propagation path, the radio wave generate path loss. In order to predict the field strength, we have to analyze the path loss of radio propagation. In this paper, a prediction system about path loss of radio propagation based on GIS is presented. The system embeds GIS technology into ITU-R P.526 model, and establishes relevant development platform. The system's major modules and experiment results are presented.
