Abstract

The spatial time-frequency distributions (STFDs) have been developed and successfully applied to high-resolution direction-of-arrival (DOA) estimations and blind recovery of the source waveforms. In [Y. Zhang et al., Aug. 2003], the spatial polarimetric time-frequency distribution (SPTFD) was introduced as a platform for space-time processing for nonstationary source signals with different polarization properties. Based on SPTFD, polarimetric time-frequency MUSIC (PTF-MUSIC) has been proposed for DOA estimation of non-coherent signals. In this paper, the use of the PTF-MUSIC is extended to the coherent signal environment using spatial and polarization averaging. Simulation results are presented to show the effectiveness of the aforementioned decorrelation techniques.
