Huge ice blades on Jupiter’s Europa will make it a right pain in the ASCII to land on

You're making a lot of assumptions there

As I read it the penitentes are near the equator (warmer environment aiding sublimation, presumably). So, at the poles the radar signal just disappears into space unless it's pointing straight down. At the equator there are vertical and horizontal surfaces forming cavities which reflect the signal randomly creating a more or less omnidirectional return signal.
