The Viking lander-to-orbiter relay links at 381 MHz made it possible to perform measurements of the electrical properties of the Martian surface by a bistatic radar technique. The fading pattern of the signal intensity received on board the orbiters via the link contains information on the reflection coefficient of the terrain in the vicinity of the lander site. To determine the electrical properties of the immediate surrounding area the observed multipath residuals were analyzed on the basis of a quasi-specular scattering theory. The relative dielectric constant was derived by performing a multiparameter computer simulation of the relay link residuals and adjusting the parameters involved in order to match this residual curve to the averaged observations. The relative dielectric constant around Lander 1 was determined to be 3.3 + or - 0.7, while that in the vicinity of Lander 2 was estimated at 2.8-12.5.
