由於雷達電磁波的散射與反射機制，造成了SAR雷達影像與光學影像的影像解譯方式有非常大的差異。因此，在SAR雷達影像中整合光學影像以補充地表相關資訊，即可強化我們對於SAR雷達影像特徵結構的瞭解。為了完成以上之目標，本研究除了詳述了雷達影像與光學影像的特性之外，還提出了一個具有多種選擇調整機制的影像融合方法--「擴充光譜調整的IHS-BT方法」，此方法利用二個可調參數的設定而提供了「衛星光學全色態影像與多光譜影像融合」、「衛星光學多光譜影像與SAR雷達影像融合」、「衛星光學全色態影像與SAR雷達影像融合」、「衛星光學全色態影像、多光譜影像與SAR雷達影像融合」等四種影像融合方式。此外，從本研究之實驗成果看出，善加調整「衛星光學全色態影像、多光譜影像與SAR雷達影像融合」方法中光學全色態影像與SAR雷達影像的資訊融合比例，可以有效的輔助本研究對SAR雷達影像中空間細節及紋理特徵的理解。

It is well known that the photo-interpretation of radar images is substantially different from the optical images due to SAR’s scattering mechanism. Merging optical images with SAR imagery can provide complementary information in order to improve understanding the structure of the features within the SAR. To achieve the goal, this research has developed an extension model of the SA-IHS-BT approach (eSA-IHS-BT) with multi-optional adjustments for image fusion. The model provides four fusion methods of Pan-MS, SAR-MS, Pan-SAR and SAR-Pan-MS by setting two parameters. Apart from that, the SAR-Pan-MS image fusion method can show better performance in assisting SAR image understanding because of reasonable contents of spatial details and texture features by tuning one parameter for adjusting the proportion of Pan to SAR image information.
