An inexpensive polarimetric FM radar and polarimetric signatures of artificial sea ice

Abstract

The authors developed an inexpensive FM radar for polarimetric scattering measurements., The system was designed for collecting polarimetric data at 5.3 and 10 GHz over incidence angles from 0 degrees to 60 degrees . The unique features of the system include fine range resolution, phase stabilization, and linearization of the RF oscillator and digital signal processing capability. The system is used for collecting polarimetric scattering data from artificial sea ice at the US Army Cold Regions Research and Engineering Laboratory (CRREL) in Hanover, New Hampshire. The authors discuss the design, construction, and performance of the polarimetric radar and present results from the CRREL experiments.<>
