The amplitude modulation (AM) reflectometer realized for the FTU tokamak has been successfully operated in a wide range of plasma conditions. The reflectometer has been calibrated using the signal reflected by the inner part of the vacuum chamber (back wall) in absence of the plasma. Density profiles have been obtained for steady-state discharges by inverting the AM phase measured as a function of the carrier frequency. The results are in good agreement with density profiles obtained from multichannel far infrared interferometry. {copyright} {ital 1997 American Institute of Physics.}
