Hybrid Dual-Polarization Synthetic Aperture Radar

open access: yesRemote Sensing, 2019
Compact polarimetry for a synthetic aperture radar (SAR) system is reviewed. Compact polarimetry (CP) is intended to provide useful polarimetric image classifications while avoiding the disadvantages of space-based quadrature-polarimetric (quad-pol) SARs.

Experimental Synthetic Aperture Radar with Dynamic Metasurfaces [PDF]

open access: yesIEEE Transactions on Antennas and Propagation, 2017
We investigate the use of a dynamic metasurface as the transmitting antenna for a synthetic aperture radar (SAR) imaging system. The dynamic metasurface consists of a one-dimensional microstrip waveguide with complementary electric resonator (cELC ...

Change Detection in Synthetic Aperture Radar Images Using a Dual-Domain Network [PDF]

open access: yesIEEE Geoscience and Remote Sensing Letters, 2021
Change detection from synthetic aperture radar (SAR) imagery is a critical yet challenging task. Existing methods mainly focus on feature extraction in the spatial domain, and little attention has been paid to the frequency domain.
