Estimation of the density of Martian soil from radiophysical measurements in the 3-centimeter range
Abstract
The density of the Martian soil is evaluated at a depth up to one meter using the results of radar measurement at lambda0 = 3.8 cm and polarized radio astronomical measurement at lambda0 = 3.4 cm conducted onboard the automatic interplanetary stations Mars 3 and Mars 5. The average value of the soil density according to all measurements is rho bar = 1.37 plus or minus 0.33 g/ cu cm. A map of the distribution of the permittivity and soil density is derived, which was drawn up according to radiophysical data in the 3 centimeter range.
