Nonstationary array processing for tracking moving targets with time-varying polarizations.
This paper presents an approach for tracking nonstationary moving sources with both time-varying directions-ofarrival (DOAs) and time-varying polarization signatures. The proposed approach is based on the spatial polarimetric time-frequency distributions (SPTFDs). Unlike the conventional correlation matrix based approaches that sacrifice the source signal polarization properties and are not properly structured to utilize polarization diversity, the proposed approach uses the signal instantaneous polarization and instantaneous frequency information for improved target tracking and polarization estimation.
