The purpose of the report is to provide an analytical basis for evaluation of the internal wave system generated by a moving body in stratified fluids which can be represented by a two-layer structure. In view of the standard representation of rigid bodies by a distribution of hydrodynamic sources, the objective is achieved by developing analytical expressions for the disturbance due to a single source. Expressions are derived for the velocity field. The method of stationary phase, when applied to these expressions, yields a simplified description of the field far behind the source. An additional quantity, the displacement function, is introduced in order to describe the amount by which fluid particles are displaced in the vertical direction from their equilibrium position.
