Automatic Registration of Mini-Rf S-Band Level-1 Data

The registration and mapping of The Miniature Radio Frequency (Mini-RF) images from The Lunar Reconnaissance Orbiter (LRO) and the derived data products has been a problem for lunar remote sensing analysis and multi-source data fusion. In this context, we propose an automated registration methodology for Mini-RF S-band level-1 data. This method corrects offsets from synthetic aperture radar (SAR) imaging to match SAR data with optical and DEM data in the map-projection. It could produce maps in polar and non-polar area with precision comparable to manually registered maps. Using manually-labeled craters features for evaluation, the processed maps match well to LRO Wide Angle Camera (WAC) and Digital Elevation Model (DEM) data on 100m- level.
