Radio propagation prediction is thought to be a basic and primary work in the research of radio wave spatial information quantitative analysis, in which, the ray tracing is one of the most effective computation method at present. The solution of radio field intensity prediction ray trace parallel computation was introduced and the bottle-neck problem about a great deal of computer work when using ray trace was aimed at. Through test, the solution can shorten the computation period effectively and makes the ray-tracing computation method of radio wave field prediction practical. 5figs., 10refs.
