FMCW Polarimetric Scatterometers
This series of FMCW scatterometers, operating from 1 GHz to 40 GHz, is designed for near range measurement of the polarimetric response of natural surfaces, such as sea ice, snow, or terrain. Scatterometers measure normalized radar cross section (NRCS) and the target Mueller Matrix (alternately the covariance matrix) as a function of incidence angle. Near field correction software allows calibrated measurements at ranges as close as 1 meter.
These instruments employ an embedded micro-computer that handles all processing tasks as well as hosting the system web page. The only connections required to operate the scatterometers are system power and Ethernet.
We recently introduced two wideband scatterometers operating at Ku-band (6 GHz bandwidth) and Ka-band (10 GHz bandwidth), having 2.5 cm and 1.5 cm resolution, respectively.
