A study of precision analysis technology of propagation variations in the multi-point measurement using a DTTB signal

Abstract

Toward the realization of a remote multi-point synchronous measurement of meteorological observations, we examined the precise analysis technique using signals in the Digital Terrestrial TV Broadcasting (DTTB). We obtains a delay profile of the digital terrestrial television broadcasting by using the band division. Then, it was analyzed the precise propagation time and propagation distance fluctuation by applying the double phase difference method.
