Due to a technical problem, Figure 1 in [1] was not published properly, i.e., color wheel in Figure 1 [1] was distorted. Remote Sensing Editorial Office would like to update Figure 1 as follows:
Original Version:
Figure 1.
Examples of lunar impact crater polarimetric images as seen from the Arecibo Observatory (a) and an m-chi classification of hybrid dual-polarized data (b) from the Mini-RF radar aboard LRO (adapted from Figure 5 of [24]). The color wheel helps to retrieve meaning from the transition colors between primaries. In this example, yellow indicates dominant contributions from both random and double-bounce backscatter.

This update does not change any scientific result of the paper. We would like to apologize for any inconvenience caused to the readers by this change.
