| Abstract: | Polarimetric SAR measures the amplitude and the phase of the scattering echo to get the complex scattering matrix or Stokes matrix of ground targets.The power with the antenna at any ellipse orientation and ellipticity angle can be calculated by using polarization synthesis.The aim of the optimization of polarization contrast enhancement(OPCE) is to find a specific configuration of transmission and reception antenna to get the best contrast between the target and the background.The paper mainly discusses the OPCE problem.An improved model and calculation method are derived.Test has been made and it proves the correctness and validity of the methods. |
| Keywords: | polarimetric synthetic aperture radar optimization of polarization contrast enhancement(OPCE) model |
