Active calibration technology for polarimetrie radar measurement

Abstract

Polarimetrie measurement is a prerequisite for applications such as radar target recognition and anti-interference based on polarimetry information. The precision of polarimetric measurement depends on the accuracy of the calibration of polarimetric radar systems. In this paper, a new polarimetric calibration method by designing a high-Precision polarimetric active radar calibrator(PARC) is proposed, which can accurately calibrate the radar transmitting and receiving channels, respectively. System composition and key technologies of the PARC are explained. And then the whole calibration method is provided.
