Qualitative comparison of secondary craters on the floor of the Peary crater from L-band DFSAR and S-band Mini-RF data. (a) L-band DFSAR Yamaguchi 4 component decomposition image with arrows in yellow denoting the anomalous (labeled “1”, “2”) and fresh craters analyzed in this work. (b) L-band DFSAR CPR image stretched to a color scale with the interior and exterior regions of interest outlined in different colored boxes as shown in the legend to its left. (c) S-band DFSAR m-chi decomposition image of the same region with arrows in yellow denoting the anomalous and fresh craters. (d) Corresponding S-band Mini-RF CPR stretched to a color scale and overlaid on the total backscatter image with the interior and exterior regions of interest. The polygons shown in (b) and (d) are used for the scatter plot shown in Figure 12. North is up, and the color scheme for decomposition images is the same as shown in Figure 8. Note that in the case of DFSAR data, we have not sampled the regions affected by artifacts (irregular red patches in the decomposition image (a)) and distorted fresh crater rim region for our statistical analysis.
