This archive contains a Pre-Magellan derived Mars radar model unit map compiled using data acquired by the 12.6-cm wavelength radar at Arecibo Observatory and the 12.9-cm wavelength Goldstone Solar System Radar.

Data Set Abstract A model for Mars depolarized radar echo power that (1) matches the observed variation of total radar cross section with longitude and (2) produces model spectra that have the broad features of spectra published for Goldstone Solar System Radar and for Arecibo Observatory 1980 to 1982 observations. This model assumes that different geologic units on Mars backscatter in a uniformly bright manner, where radar echo power is A * Cosine (angle of incidence), where A varies across the planet. This model assigns depolarized radar echo power on a degree-by-degree basis in latitude and longitude.
