In the letter the performance of the Fougere method for autoregressive (AR) spectral analysis is studied. This method is compared with the Burg method and the least-squared (LS) method (Marple algorithm). It is shown that when the signal consists of two equal-level sinusoids in white noise and the data are complex-valued, as they will be in antenna applications, the Fougere method improves the results obtained by the Burg method in all cases. Also, for low signal/noise ratio (SNR), the Fougere method gives better results than LSM.
