Highway Bridge Detection Based on PCA Fusion in Airborne Multiband High Resolution SAR Images

This paper proposes a method for bridge detection in airborne multiband high resolution SAR images based on PCA fusion. Images are obtained simultaneously by three bands, which are L(HH), C(HH) and X(VV), with resolution 1 meter. The paper compares the efficiency of bridge detection from different band firstly. Then, the PCA fusion of multiband is implied to detect bridge. The results show that PCA fusion is an effective method in this case.
