| Abstract(in English) | The authors are developing a method to estimate water vapor (propagation delay due to water vapor) using digital terrestrial broadcasting waves. A precise measurement of the phase differences between the direct waves from the radio tower (e.g., Tokyo Skytree) and the reflected waves from reflectors enables us to obtain the time variations of propagation delay due to water vapor with high temporal resolutions. For using the reflected waves, the identification of reflectors is important. In this paper, a method to estimate angle of arrival (AOA) for the purpose of identification of the reflector is reported. |
