General Calibration Algorithm for Single-transmitting-dual-receiving Polarimetric SAR System
Leida xuebao, 2012 The single-transmitting-dual-receiving polarimetric SAR system has only two receving channels, which induces lack of prior information for calibration. Due to the polarization diversity of this kind of system (which operates on different dual and compact

Pupil Plane Multiplexing for Vectorial Fourier Ptychography
Laser &Photonics Reviews, EarlyView.This study proposes a cost‐effective, modality‐adaptive multichannel microscopy framework using pupil‐plane multiplexing. A custom pupil aperture at the Fourier plane encodes channel‐specific transfer functions with spectral or polarization filters, and model‐based reconstruction with channel‐dependent priors decodes them.

A Novel Point Target Attitude Compensation Method Using Electromagnetic Reflectance Theory
Remote Sensing, 2023 During the process of the airborne synthetic aperture radar (SAR) system platform in space, platform attitude deflection is inevitable. However, large attitude deflection angles are unacceptable for polarimetric calibration using point targets ...

Calibration of radars using polarimetric techniques [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 1992 A method that uses the properties of rain medium itself to obtain accurate weather radar system gain calibration is discussed. This technique is based on the principle that the rainfall rate measured using absolute reflectivity (Z) and differential reflectivity (Z/sub DR/) is the same as that obtained from specific differential phase (K/sub DP/).
