Compression Method for High Dynamic Range Intensity to Improve SAR Image Visibility
Satoshi Hisanaga, Koji Wakimoto, Koji Okamura · 2015
Abstract—It is possible to interpret the shape of buildings based on synthetic aperture radar (SAR) images acquired using airborne SAR systems. However, the pixel values of SAR images have high dynamic range intensity, and SAR images are not displayable without dynamic range intensity compression. We therefore have developed a dynamic range intensity compression method suitable for SAR image features. Using our method, the visibility of SARs images has been improved. Index Terms—synthetic aperture radar, visualization, dy-namic range intensity compression. I.
