With the development of ocean exploration and research, the precise estimation of underwater electromagnetic sources’ DOA and polarization has become an essential research topic. An electromagnetic vector sensor can measure all six electromagnetic field components of the incident wave field. Thus, it explores not only the DOA of the signal but also the polarization diversity which represents electromagnetic sources’ specific distribution. TLS-ESPRIT algorithm is based on rotation invariant of two signal subspaces. It utilizes a pair of temporally displace data sets collected form a single electromagnetic vector sensor. The parameter estimates are obtained through Poynting vector that is cross-product operation of each signal subspace eigenvector of the data correlation matrix. This method requires no priori knowledge of signal frequencies, suffers no frequency ambiguity, can resolve up to five uncorrelated monochromatic underwater sources. Simulations illustrated the efficiency of the algorithm.
