The Miniature Radio Frequency (Mini-RF) system is manifested on the Lunar Reconnaissance Orbiter (LRO) as a technology demonstration and an extended mission science instrument. Mini-RF represents a significant step forward in spaceborne RF technology and architecture. It combines synthetic aperture radar (SAR) at two wavelengths (S-band and X-band) and two resolutions (150 m and 30 m) with interferometric and communications functionality in one lightweight (16 kg) package.

Miniaturized Radar, Outsized Results
The Mini-RF instrument is a Synthetic Aperture Radar that was awarded “technology demonstration” status onboard NASA’s Lunar Reconnaissance Orbiter (LRO) and the POC systems were scaled to meet the increased demands, enabling Mini- RF to support opportunity targeting and to map large portions of the Moon at both the polar and equatorial regions.

Bistatic Radar Observations of the Moon Using Mini-RF on LRO and the Arecibo Observatory
The Miniature Radio Frequency (Mini-RF) instrument aboard NASA's Lunar Reconnaissance Orbiter (LRO) is a hybrid dual-polarized synthetic aperture radar (SAR) that operated in concert with the AreciboExpand
Radar Moon bounce operations process
A campaign to observe the Moon in concert with a ground-based radar asset (Arecibo Observatory) using a bistatic architecture presents unique challenges to both planning for data acquisition and processing downlinked data to form a radar image of the lunar surface. Expand

Generating lunar bistatic SAR images using Arecibo and Mini-RF
We have employed the Arecibo Observatory Planetary Radar (AO) transmitter and the Mini-RF radar onboard NASA's Lunar Reconnaissance Orbiter (LRO) as a receiver to collect bistatic data of the lunarExpand


Mini-SAR: an imaging radar experiment for the Chandrayaan-1 mission to the Moon
Mini-SAR is a single frequency (S-band; 13-cm wavelength) Synthetic Aperture Radar (SAR) in a lightweight (~9 kg) package. Previous Earth- and space-based radar observations of the permanentlyExpand
Reanalysis of Clementine bistatic radar data from the lunar South Pole
On April 9, 1994, the Clementine spacecraft high-gain antenna was aimed toward the Moon's surface, and the resulting 13-cm wavelength radio echoes were received on Earth. Using these data, we haveExpand
The Clementine Bistatic Radar Experiment
Analytical analysis shows that the observed enhancement is localized to the permanently shadowed regions of the lunar south pole, and that observations of periodically solar-illuminated lunar surfaces, including the north pole, yielded no enhancement. Expand

Integration of lunar polar remote‐sensing data sets: Evidence for ice at the lunar south pole
In order to investigate the feasibility of ice deposits at the lunar south pole, we have integrated all relevant lunar polar data sets. These include illumination data, Arecibo ground-basedExpand
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 shadowExpand
No evidence for thick deposits of ice at the lunar south pole
New 20-m resolution, 13-cm-wavelength radar images are presented that show no evidence for concentrated deposits of water ice in Shackleton crater or elsewhere at the Moon's south pole, consistent with the ice being present only as disseminated grains in the lunar regolith. Expand
