PROBLEM TO BE SOLVED: To provide a detouring transmission line estimation device for estimating a detouring transmission line, which not only starts or restarts under the constraints of existing broadcasting system, and the like, but also adapts flexibly to variation in the characteristics with time or due to the environment, thus achieving accurate and stable transmission line estimation of a detouring path.SOLUTION: A detouring transmission line estimation device includes control means for setting the carrier frequencies of a transmission wave radiated from a second antenna, under retransmission or relay of an incoming wave from a first antenna, to a plurality (p) of different values f-findividually in the order of time series, and estimation means performing transmission line estimation of a path as the resolution of a simultaneous equation consisting of a plurality (p) of expressions, indicating the total characteristics of the system performing retransmission and a detouring path from the second antenna to the first antenna, and reflecting the plurality (p) of different values f-findividually. |
