Zusammenfassung:The invention relates to the field of urban radio wave propagation prediction, in particular to a data model hybrid-driven radio wave propagation actual measurement correction method, which comprises the following steps of: performing environment modeling on a to-be-calculated area, performing simulation calculation on a plurality of receiving points by using a ray tracing algorithm, and calculating a plurality of receiving points; receiving points are divided into a direct wave group and a non-direct wave group according to multipath type characteristics, actually measured power values are collected, then error values of the actually measured power values of a correction group and a verification group are calculated according to different grouping strategies, simulation values of the verification group and all the receiving points are corrected by adopting an inverse distance weighted interpolation method, and the verification group and all the receiving points are corrected. Therefore, the precision of radi
