Summary: We propose a very simple generalization of the one-dimensional multitaper spectral estimation technique to the multidimensional case. Multidimensional tapers are constructed from products of one-dimensional taper elements, or formally as outer products of lower dimensional tapers. The two-dimensional case is treated in some detail, and several properties of the novel tapers are listed.
