This paper investigates the polarimetric bistatic scattering characteristics of layered random media. On applying the Born approximation, we have calculated the bistatic Mueller matrix of a half-space random medium. The power received by a receiving antenna is the quantity chosen to optimize. The variables of the problem are the polarizations of the transmitting and receiving antennas. For the case when the polarizations of the transmitting and receiving antennas are identical, we have calculated the optimum polarizations and we have found that the optimum polarizations include both linear and elliptical polarizations. The conditions for maximum and minimum received power are also obtained. In the backscattering case, we have considered the situation when the transmitting and receiving antennas have independent polarizations. For a two-layer problem, we have observed the influence of the thickness of the layer in the classification of the optimum polarizations.
