  We introduce multilinear localization operators in terms of the short-time
Fourier transform, and multilinear Weyl pseudodifferential operators. We prove
that such localization operators are in fact Weyl pseudodifferential operators
whose symbols are given by the convolution between the symbol of the
localization operator and the multilinear Wigner transform. For such
interpretation we use the kenrel theorem for the Gelfand-Shilov space.
Furthermore, we study the continuity properties of the multilinear localization
operators on modulation spaces. Our results extend some known results when
restricted to the linear case.
