Abstract: Abstract: It has been pointed out by many researchers that there are many advantages to use a marine to
measure wave field characteristics in coastal regions. However, monitoring wave fields through radio
wave reflections belongs to the category of indirect measurements. Just like all other similar methods,
the results acquired from these kind of measurements are not actual physical quantities of interest.
Some transfer function(s) must be used so that the real world can be recovered. The NTOU has
started analyzing radar images in order to obtain information of the wave field around Taipei Harbour.
Previous studies have shown that althrough discrepencies between measured and estimated significant
wave heights exist, the latter follows the trend of the former. Nontheless, the results also show that
there are times where estimated wave heights were unrealistically highere than those measured. In
this paper, we reanalyzed the radar images available. It is shown that the present results are more
satisfactory.
