From the mission description:

"Bistatic surface scattering will be observed at low southern latitudes on the ingress side (25-30 degrees; ~90-110 degrees west longitude) and low northern latitude (25-30 degrees; ~200-220 degrees west longitude) on the egress side."
Bistatic experiments can be used to infer dielectic constant. Dielectric constant tells you how polar the material is: water being very polar with a large dielectric constant, hydrocarbon being non-polar with a low dielectric constant.
[-25- -30S, 90-110W] is just a tad to the NW of Hotei Arcus, Xanadu. If this is a cryo-caldera (like Yellowstone or Craters of the Moon) with expesed cryobasalt, you'd expect a lot of exposed high-dielectric constant ice.
[25-30N. 200-220 W] is in the Dilmun peninsula just a tad WNW of the Dancing Monkey (or Flying Spaghetti Monster) feature. Depending on the resolution, you might see if the dark pattern forming the Dancing Monkey are composed of low dielectric constant dune sands or higher dielectric constant exposed water ice. (I favor an even lower dielectric constant organic tar fill. I think this might be Deep Black unit deep in the cracks.)
