METHOD AND DEVICE FOR GEOMETRICAL-OPTICAL RADIOWAVE PROPAGATION CHARACTERISTICS ANALYSIS, AND RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for geometrical-optical radiowave propagation characteristics analysis of high speed and precision, as well as a recording medium.;SOLUTION: In a pre-process 101 of geometrical-optical radiowave propagation characteristics analyzing method, a pseudo beam 1 is radiated from a transmission point 201 at such radiative discrete angle as at least one pseudo beam 1 collides with all obstacles for a radiowave propagation analyzing process 102. The number of main pseudo beams 104 at the specified level or higher and radiation direction 105 are recorded on a recording device 103 at a reception point. In a post process 106, the number of main pseudo beams 104 and the radiation direction 105 of main pseudo beams that are recorded in the recording device 103 are read. The pseudo beam is radiated only in the direction 105 of main pseudo beam at a specified high density, for the radiowave propagation analyzing process 102.;COPYRIGHT: (C)2006,JPO&NCIPI
