Martian craters and a scarp as seen by radar.
Radar observations of Mars with a surface resolution of 1.3 degrees in latitude and 0.8 degrees in longitude have been carried out during the opposition of 1971. With a precision in surface height measurement approaching 75 meters in regions of high reflectivity, it has been possible to measure the detailed characteristics of a number of craters. Many of these can be identified with craters shown in Mariner photographs of Mars. In addition, a scarp has been seen at 41 degrees west, 14 degrees south with an average slope of about 6 degrees extending over about 40 kilometers.
