A robust, spectral method of analysing cyclostationary time-series is introduced. The robust method involves an adaptation of an autoregressive one-step ahead predictive cleaning process. Standard, robust spectrum estimates are compared against the robust estimate computed using the presented procedure and found to be inferior, both in simulation and on seismic velocity data obtained from station NNA, situated in Ñaña, Peru.
