New expressed nonlinear polarization vector translation and its application in HF Radar

The nonlinear polarization-vector translation algorithm proposed by A.J. Poelman is expressed by ellipticity ratio and orientation angle on a right-handed circular/left-handed circular polarization vector basis. It is inconvenient in the processing of signals expressed by the polarization parameters of amplitude-ratio and relative phase on a horizontal/vertical polarization vector basis. A new expressed NPVT algorithm is given to solve this problem in this paper, and the relation between the two NPVT algorithms is described mathematically. A good performance is obtained by the application of the new algorithm in suppressing of sky-wave radio interference in an HF surface wave radar compared with some other polarization filters.
