The Direction, carrier frequency and polarization information of multi-sources are all required for many systems such as electronic surveillance. Based on one crossed dipole sensor array, a tempo-spatial expanded virtual sensor array is built, so a novel method for 2-Dimentional (2-D) Direction Of Arrive (DOA) angle, carrier frequency and 2-D polarization angle estimation is proposed. The aperture of virtual array is several times to that of real ones, so it is more suitable for multi-sources parameters estimation in high noisy environments. The estimations of all these parameters can be got simultaneously, and automatically paired in calculating process with no spectrum searching. Similar performance with ESPRIT method can be achieved by least calculating burden, or far higher performance by high calculating burden. This algorithm can be used to any plane sensor array and this character would be very useful for applications. Simulations were presented to show the capabilities of this method.
