heal.abstract	The Wigner Transform (WT) has been extensively used in the formulation ofphase-space models for a variety of wave propagation problems includinghigh-frequency limits, nonlinear and random waves. It is well known that the WTfeatures counterintuitive 'interference terms', which often make computationimpractical. In this connection, we propose the use of the smoothed WignerTransform (SWT), and derive new,	en
