Abstract
A high-resolution fully polarimetric frequency modulation continuous wave (FMCW) image radar system using an RF switch and an image processing method are provided. The image radar system includes a signal generator that generates a frequency modulation signal, a transmitter that radiates the frequency modulation signal as vertical polarization and horizontal polarization using a vertically polarized transmit antenna and a horizontally polarized transmit antenna, a receiver that receives a signal in which a vertically polarized signal and a horizontally polarized signal are reflected from an object, using a vertically polarized receive antenna and a horizontally polarized receive antenna, and generates a VV/HV polarization data set and a VH/HH polarization data set based on the signal received via the vertically polarized receive antenna and the horizontally polarized receive antenna, and a signal processor that obtains a fully polarimetric radar image based on bilateral symmetry correction and azimuth compression.
