	Resumo
	A 2 two-dimensional finite-differences time-domain full-wave code has been developed to simulate microwave reflectometry diagnostic in fusion plasmas, aiming at the following objectives: understanding physical effects, improving profile measurements, assessing signal processing techniques and devising new applications for reflectometry. The bases of the code as well as its computational implementation are described. An example is presented where the code is used to simulate density profile measurements in the presence of turbulence and to assess the behavior of the burst-mode data analysis tool, used in ASDEX Upgrade tokamak, to improve the accuracy of profile measurements distorted by plasma turbulence. It is shown that the code validates the burst mode analysis and establishes the domain where this data processing is applicable.
