Radar glories on jupiter's moons
"Three ice-covered moons of Jupiter, in comparison with rocky planets and the Earth's moon, produce radar echoes of astounding strengths and bizarre polarizations. Scattering from buried craters can explain these and other anomalous properties of the echoes. The role of such craters is analogous to that of the water droplets that create the apparition known as 'the glory,' the optically bright region surrounding an observer's shadow on a cloud."
Eshleman, Von R.; "Radar Glory from Buried Craters on Icy Moons," Science, 234:587, 1986.)
