An L-shaped array is used to estimate azimuth-elevation angles and polarisation of multiple narrow band waves. A 2-D weighted subspace filling (WSF) method is used to estimate the parameters. Performances improve above WSF without polarisation information and above other DOA methods with polarisation information such as MUSIC or Matrix-Pencil by reducing the number of snapshots and detecting coherent sources with low SNR. Its reachness to the Cramer-Rao lower bound (CRB) shows the goodness of the method.
