摘要：

A pulse compression method is proposed to simulate the propagation of a pulse in an inhomogeneous plasma. It allows very fast computations compared to the usual time-dependent code. The characteristics as well as the limitations of this method are discussed. In particular the phase shift of the pulse frequency components is analyzed for different kinds of density profiles. The validity of using this method under typical conditions in fusion plasmas is then discussed. (C) 2001 Elsevier Science.
