PURPOSE: To facilitate device movement at the time of measurement in a multiple propagation characteristic measuring device for measuring the propagation characteristics of a propagation line for generating multipath phasing in mobile object communication. CONSTITUTION: A transmission means 1 sends out transmission signals composed of discrete frequency spectrum components to the propagation line. A relay means 2 receives the transmission signals while moving, shifts a frequency so as not to overlap on a frequency axis for the reception signals and sends them to a reception means 3. By the movement of the relay means 2, the reception signals receives the multipath phasing. The reception means 3 incorporates an analysis device and acquires the multiple propagation characteristics of the propagation line by analyzing the signals sent from the relay means 2. Since the analysis device is provided in the reception means 3, the moving relay means 2 is turned to small-scale constitution and thus, the device movement at the time of the measurement is facilitated. |
