“…In addition, the complexity and costs of polarimetric systems restrict our ability to obtain the measurements required to understand the variation of the polarimetric signatures associated with natural and artificial surfaces and targets as a function of the surface type, the state of the surface, and the environmental conditions. Using a passive or active polarimetric system it is possible to infer surface winds over ocean areas 1 , study the spatial scale of microwave brightness temperatures in boreal forests 2 , analyze precipitation characteristics 3 , and determine soil moisture 4 . This paper presents the polarimetric signatures of natural and artificial surfaces and targets measured using 35 and 94 GHz Direct Detection Polarimetric Radiometers (DDPR).…”

Polarimetric signatures of terrain features and man-made objects have been measured using unique Direct Detection Polarimetric Radiometers (DDPR). The DDPRs are lightweight inexpensive systems operating at 35 and 94 GHz. Each system consists of a single antenna, amplifier, and a truncated cylindrical waveguide that directly measures Q, U, and V. The highly portable DDPRs are ideal for obtaining the Stokes vectors needed to study the physical characteristics of natural and man-made features. Field evaluations using the DDPR systems include measurements from an airborne platform over different terrain features and water, and ground based measurements of the polarimetric signature of grass, asphalt, buildings, and concealed munitions. The DDPR can function as a bistatic system by using an active source of polarization. Using this configuration and a soil chamber, we have investigated the effect of soil type and soil moisture on linear and circular polarization. This report will describe the DDPR and present the analysis of the airborne and ground based measurements, including the effects of soil type and soil moisture on sources of linear and circular polarization.

Calculations of attainable values for space resolution and radiometric sensibility of a spaceborne two‐dimensional synthetic aperture microwave polarimetric interferometer are carried out. It is shown that for the most preferable Y‐shaped interferometer configuration, it is possible to achieve (within the transparency windows of waveband 3–22.5 mm) a space resolution of 0.5–1 km and a radiometric resolution close to 1 K at the receiver bandwidth of 100 MHz. For cross‐ and T‐shaped resolutions, values close to the above can be reached.
