Abstract :
This paper explores a unique calibration method for polarimetric radar without requiring any calibration targets. The error of the polarimetric scattering matrix measurement is modeled as antenna distortion matrices and channel distortion matrices. These distortion matrices can be determined using a signal generator in anechoic chamber. The performance of the calibration method is analyzed by simulation. Its validity is verified through the experiment of an X-band polarimetric radar system.
