Mission Overview
============================

This entity is a collection of selected Earth-based radar data of Venus, the Moon, Mercury, and Mars, Pioneer Venus radar data, airborne radar images of Earth, and line of sight acceleration data derived from tracking the Pioneer Venus Orbiter and Viking Orbiter 2. Included are 12.6 centimeter wavelength Arecibo Venus radar images, 12.6 to 12.9 cm Goldstone Venus radar images and altimetry data, together with altimetry, brightness temperature, Fresnel reflectivity and rms slopes derived fromthe Pioneer Venus Radar Mapper.

For the Moon, Haystack 3.8 centimeter radar images and Arecibo 12.6 and 70 centimeter radar images are included. Mars data include Goldstone altimetry data acquired between 1971 and 1982 and a raster data set containing radar units that model Goldstone and Arecibo backscatter observations. Mercury data consist of Goldstone altimetry files. The terrestrial data were acquired over the Pisgah lava flows and the Kelso dune field in the Mojave Desert, California, and consist of multiplefrequency, multiple incidence angle views of the same regions.

Data set documentation is provided, with references that allow the reader to reconstruct processing histories. The entire data set collection and documentation are available on a CD-ROMentitled Pre-Magellan Radar and Gravity Data.
