Shallow Radar (SHARAD)

NSSDCA ID: 2005-029A-05

Mission Name: Mars Reconnaissance Orbiter
Principal Investigator:Dr. Roberto Seu


The Shallow Radar (SHARAD) instrument is a nadir looking synthetic aperture radar sounder designed to probe beneath the martain surface to a depth of up to one kilometer for liquid or frozen water. SHARAD will operate by transmitting radar waves in the 15-25 MHz band towards the surface at a peak radiated power of 10 W. Reflections from the surface and subsurface are sensitive to changes in electrical properties and density, allowing detection of water and geologic layers. The horizontal resolution of the instrument is between 0.3 and 3 km and the vertical resolution is 15 meters. The instrument consists of an antenna composed of a dipole radiating element, a transmitter, receiver, analog-to-digital converter, and command and control devide. SHARAD is being provided by the Italian Space Agency (ASI).
