Mutual Coupling Calibration and Remedy Method for Polarization Sensitive Sensors

A mutual coupling calibration algorithm for polarization sensitive sensors is proposed in this paper. By introducing into an auxiliary element and using a calibration source with unknown parameters, the mutual coupling is calibrated. A mathematic model for mutual coupling across the six collocated antennas of a polarization sensitive sensor is established. And the solution of mutual coupling matrix was transformed into the solution of several matrix elements. The simulation results demonstrate this approach is effective.
