A channel characteristic analyzing apparatus that can ensure modeling of a more adequate propagation path by processing position parameters needed in a two-wave model which is used as a line-of-sight propagation path model in a stochastic manner is provided. The channel characteristic analyzing apparatus for analyzing the propagation channel characteristics of a reception apparatus 11b which has received a radio signal of a millimeter wave band, transmitted from a transmission antenna 13a of a transmission apparatus 11a, via a reception antenna 13b, includes computation means which computes h(t) expressed by the following equation (1) as a channel response to the propagation channel characteristic. h(t)=.beta..delta.(t) (1) where .beta. is derived as a result of processing the position parameters needed also in the two-wave model in the stochastic manner.
