Abstract
Transmission of a signal in the right-circularly polarized mode using the Polarization Diversity S-Band (PDS) cone in fact results in a slightly elliptically polarized wave. After reflection from a distant surface and return to the antenna, the expected wave polarization is left-circular, Upon reception, a small component of right-circular polarization is present, and is partly the result of transmitting a small left-circular component. A similar fraction of the received left-circular wave is coupled into the received right-circular polarization. The total power in the received right-circular component is 1.2 +0.2% of the power in the received leftcircular component. The instrumental polarization is then 0.6 +0.1%. The data leading to this result were obtained between July and November 1973 by transmitting radar signals to the planet Mars and subsequently measuring the power in the reflections.
