Abstract
The field measurement is important to evaluate the reception environment of the terrestrial digital broadcasting. This system revolves the directional antenna for the measurement, and measures it by the synchronizing method using the feature of digital broadcasting. The feature is a technique for the continuous record and analyzing the antenna azimuth and the reception signal, and the measurement time is also extremely short in a horizontal plane for about one minute from 30 seconds. As a result, the direction where the multi-pass comes can be analyzed.
