| Abstract: | A joint estimation method of polarization and 2D （two-dimensional） DOA was proposed for arbitrary array. Based on the space-time eigenstructure of signals, space-time matrixes were constructed by spatial domain sampling and time domain sampling. The DOA matrix method was utilized to estimate the parameters in this method. It doesn＇t need spectral peak searching and complex computation, The simulation validated effectiveness of this method. |
