Abstract

An inexpensive dual-frequency FM radar called PAIR (polarization-agile instrumentation radar) and a step-frequency radar based on an HP-8753B network analyzer were developed for polarimetric scattering measurements. These systems were designed to operate at ranges between 3 and 6 m and for collecting data over incidence angles from 0 degrees to 60 degrees . The FM radar was developed for operation at center frequencies of 5.3 and 10 GHz, and the step-frequency system was developed for operation at 5 and 13.6 GHz. These systems were used to measure backscattering from artificial sea ice. The authors present the design considerations, system performance, system calibration, and results from the experiments over artificial sea ice.<>
