JET’s frequency-modulated continuous-wave (FMCW) reflectometers have been operating well with the current design since 2005 and density profiles are being automatically calculated intershot since then[1]. However, the calculated profiles had long suffered from several shortcomings – poor agreement to other diagnostics; sometimes inappropriately moving radially by several centimetres; elevated level of radial jitter; and persistent wriggles (strong unphysical oscillations in the reconstructed density profiles), sometimes associated, but not exclusive, to band junctions. This contribution goes through several aspects modified in the data analysis that resulted in significant suppression of all these issues.
