Because Venus is shrouded by a dense, opaque atmosphere, conventional optical cameras cannot be used to image its surface. Instead, Magellan's imaging radar uses bursts of microwave energy somewhat like a camera flash to illuminate the planet's surface. The radar pulses are not sent directly downward but rather at a slight angle to the side of the spacecraft--the radar is thus called 'side-looking radar.' In addition, special processing techniques are used on the radar data to result in higher resolution as if the radar had a larger antenna, or 'aperture'; the technique is thus often called 'synthetic aperture radar,' or SAR. The Magellan mission was managed for NASA by the Jet Propulsion Laboratory (JPL), Pasadena, CA.

Gaps in the Magellan coverage were filled with images from the Earth-based Arecibo radar in a region centered roughly on 0 degree latitude and longitude, and with a neutral tone elsewhere (primarily near the south pole). The composite image was processed to improve contrast and to emphasize small features, and was color-coded to represent elevation. Gaps in the elevation data from the Magellan radar altimeter were filled with altimetry from the Venera spacecraft and the U.S. Pioneer Venus missions.
