A radio wave monitoring apparatus includes a communication quality evaluation unit which notifies degradation of communication quality of wireless communication when a non-transmission probability exceeds a threshold, the non-transmission probability having been calculated based on measurement results of communication quality of wireless communication between an on-board station mounted on a train traveling on a track and ground stations installed along the track, and a condition by which it is determined that transmission information is unreachable in the wireless communication.
