  11. However, df pre - processing is not required in a interferometer direction finder. it only makes use of the phase relations or differences of sensors disposed at different position. azimuth and elevation are caculated from the phase differences or displayed directly on a crt drived by the voltage or current from the phase differences

    干涉儀測向不必進行測向信號預處理而是直接或間接求取在空間上分開的傳感器上感應電勢之間的相位關系，即干涉相位差，方位角或仰角是直接由干涉相位差計算得到，或將兩基線正交的天線陣的干涉相位差轉化為驅動電壓（電流）分別加到crt陰極顯示器的垂直偏轉線圈和水平偏轉線圈，模擬顯示出來波方位，干涉儀測向為典型的相位測向方法。
