Abstract (in Japanese) (See Japanese page) 
(in English) A water vapor measurement system using digital terrestrial broadcasting wave is under investigation. A real-time delay measurement system with software-defined radio technique is developed. Water vapor between two receiving points can be estimated by synchronization between their local oscillators. In this paper, experimental results using reflected waves are reported. We succeed in observing the delay due to water vapor between observing point and reflector using the balance between phases of direct waves and reflected waves.
