Being propagation path presumption manner and the propagation path presumption

摘要

PROBLEM TO BE SOLVED: To provide a propagation path estimation method, program and device which can quickly estimate a propagation path in a propagation analysis model containing a direction control scatterer.;SOLUTION: A propagation path estimation method according to the present invention includes a process in which, when a structure exists in a propagation path from a radio wave transmit point TX to a receive point RX, whose reflection or scattering direction relative to a radio wave incident direction θ_i is a direction θ_r=f(θ_i) differing from a mirror reflection direction θ_r=θ_i, and when the incident and reflection angles of the structure at its true reflection point P_op are assumed to be θ_iop and θ_rop=f(θ_iop), respectively, a true reflection point P_op is determined using the sum of h_T×tan(θ_iop) and h_R×tan(f(θ_iop)) and the relationship between the incident angle θ_iop and the reflection angle θ_rop.;COPYRIGHT: (C)2012,JPO&INPIT
