Virtual Polarization Technology in Adaptive Polarization Radar System

Adopting optimal polarization state can be highly conducive to anti-interference as well as target enhancement while virtual polarization is an effective method to realize adaptive polarization decision in radar system. It can freely vary the polarization state of received waves to match targets’ polarization characteristics or be orthogonal to interference polarization state on the purpose of promoting SIR. This paper has not only made thorough research on virtual polarization’s concepts and principals but also presented its specific realization methods as well as application in radar system.
