The first unambiguous full-disk radar mapping of Mercury at 3.5-centimeter wavelength, with the Goldstone 70-meter antenna transmitting and 26 antennas of the Very Large Array receiving, has provided evidence for the presence of polar ice. The radar experiments, conducted on 8 and 23 August 1991, were designed to image the half of Mercury not photographed by Mariner 10. The orbital geometry allowed viewing beyond the north pole of Mercury; a highly reflective region was clearly visible on the… 
Mercury: Full-disk radar images and the detection and stability of ice at the North Pole
The first full-disk radar images of Mercury were obtained on August 8 and 23, 1991. These images were constructed using the Very Large Array (VLA) in Socorro, New Mexico, to receive and map radar
Radar imaging of the planets using the Very Large Array [invited]
We have used the VLA to make images of the planets which are continuously illuminated by the high power planetary radar transmitter on the 70 meter antenna at Goldstone, CA. That instrument is
Arecibo Radar Mapping of the Lunar Poles: A Search for Ice Deposits
The Arecibo 12.6-centimeter wavelength radar system was used to image the polar regions of the moon at a resolution of 125 meters in a search for ice deposits in areas of possible permanent shadow
High-Resolution Radar Imaging of Mercury's North Pole
Abstract The recently upgraded Arecibo S-band (λ12.6-cm) radar was used to make delay-Doppler images of Mercury's north polar region, where earlier observations had shown strong echoes from putative

Radar Images of Mars
TLDR
Full disk images of Mars have been obtained with the use of the Very Large Array (VLA) to map the radar reflected flux density, revealing near-surface features including a region in the Tharsis volcano area that displayed no echo to the very low level of the radar system noise.
High-resolution radar maps of the lunar surface at 3.8-cm wavelength
The entire earth-facing lunar surface has been mapped at a resolution of 2 km using the 3.8-cm radar of Haystack Observatory. The observations yield the distribution of relative radar backscattering
The Thermal Stability of Water Ice at the Poles of Mercury
TLDR
Thermal model calculations show that, despite Mercury's proximity to the sun, the temperatures of flat, low-reflectivity surfaces at Mercury's poles are not expected to exceed 167 kelvin, which is consistent with the presence of water ice.
Radar Observations of Mercury.
Pure monochromatic waves of a wavelength of 12.5 cm were beamed toward the planet. The echoes were no longer monochromatic because of the Doppler effect of the planet's rotation. A Fourier power

TLDR
The complete body of data favors the preliminary conclusion that Mercury has an intrinsic magnetic field, which represents a major scientific discovery in planetary magnetism and will have considerable impact on studies of the origin of the solar system.
