Radar images are typically byte images of some sort.
Radar data is in a different format, sometimes due to the nature of the data. For polarimetric radars , the data volume of radar data can be quite large compared to a byte image. However, there may be a great deal more information than is present in the byte images. Imaging radars provide a unique way of looking at the Earth and other planetary bodies. An imaging radar works very like a flash camera in that it provides its own light to illuminate an area of interest and take a snapshot picture, but at radio wavelengths.
