Abstract
Dropped-channel polarimetric synthetic aperture radar (PolSAR) compressed sensing (CS) [1], [2] recovers an unmeasured polarimetric channel by utilizing antenna crosstalk and CS techniques. A sufficient amount of crosstalk is required for successful recovery; however, dual-polarized antennas are typically designed to have very good channel isolation. A new antenna is needed that can provide high crosstalk without sacrificing gain, bandwidth, and radiation pattern. In this paper, we design a new, high crosstalk, dual-polarized patch antenna, using Ansys/HFSS to optimize pin placement and patch size for the desired gain, center frequency, and crosstalk values. The designed antenna is constructed, and S-parameters, gain, and radiation patterns are measured. The measured crosstalk values are then tested in the dropped-channel PolSAR CS model over a few deterministic scenes, demonstrating sufficient expected performance of the physical antenna for sparse scene recovery.
