Abstract A new approach with high resolution 2-D spectrum estimation is presented. Based on the array signal processing and the eigenstructure decomposition method, the signal subspace and the noise subspace are achieved by reconstructing and decomposing the data matrix collected by the array sensors. By using the orthogonal properties of the two subspaces, the information about the velocities and bearings of spatial moving targets can be exactly obtained. This method is applied to phased array radars. The computer simulation results demonstrate its availability.
