　　本研究採用都卜勒微波雙雷達遙測系統，分別在93年4月10日與93年5月11日於安平港港口，在不影響船隻進出的情形下，觀測港口表面流場。
　　不同內插法，對於流場圖的解析度會有影響。鄰近點內插法解析範圍會比其他方法範圍大，但速度向量較不具連續性，線性幾何內插法其解析範圍較小，但較符合流場的連續性，而三維三次內插法其解析範圍同線性幾何內插法，但流場最符合流體的連續性。本文使用三維三次內插法。
　　由4月10日觀測結果，可清楚了解安平港港口於漲退水時的流場特性，流速較大的範圍位於港口中主航道之區域。而由5月11日的觀測結果可得知，出海口與主航道，港口內外不同的流況特性。

　　Extending the dual Doppler Microwave Radars Remote sensing technique used in coastal water, this study applies the same system to measure tidal surface flow field of An-Ping Harbor without influencing voyage of ships on 4/10/2004 and 5/11/2004.
　　Methods for interpolation would make influence upon the resolution of flow field plot. The analytic range of nearest-neighbor interpolation is wider than others, but velocity vector is less continuous. That of linear interpolation is narrower; however its continuity is better. The analytic range of cubic interpolation is as wider as that of linear interpolation, but the continuity is most satisfying. Therefore in this article cubic interpolation is applied.
　　With the measurements on 4/10/2004, we can understand the characteristics of flow field of An-Ping harbor at ebb and flood tide. Faster currents occur mainly at the dredged deep channel. The measurements of 5/11/2004 show the tidal flows are moving mainly at the inside and outside of the harbor inlet, and at the deep channel. At other areas, however, the flow velocities are comparably small. According to the above results, it is known that the narrow inlet restricts ebbing water to move out of the harbor so flow becomes more complex at ebb tide.
