SHARAD3D – SHARAD 3D Radar Images

PDS Data Set ID:MRO-M-SHARAD-5-3D-V1.0DOI: 10.17189/qk73-zx21

The MRO SHARAD 3D radar dataset contains three-dimensional volumes of radar sounding data for Mars collected by the SHARAD instrument on the Mars Reconnaissance Orbiter. Each 3D radar volume consists of an amalgamation of data collected over many SHARAD tracks crossing a given projected area. Each 3D volume contains values of the radar backscatter power, strength, or amplitude arranged in an array with either time delay or depth on the fastest varying (Z) axis, the projection X coordinate on the slowest varying axis, and the projection Y coordinate on the intermediately varying axis. The label file for each 3D volume contains information about the axes sampling intervals, projections, and data scaling. In the BROWSE directory, there are a series of JPEG-format images excerpted from each volume, showing 2D radargrams for every 100th sample in the X and Y directions and a radar time-delay or depth slice (map view with values at all X and Y locations) for every 25th sample in the Z (time delay or depth) dimension. The name of each browse image contains the corresponding X, Y, or Z index value. Each JPEG image has an accompanying label file.
