The disclosure relates to a process of cyclic detection in diversity of polarization of digital cyclostationary radioelectric signals. The process consists in acquiring the signals on a network of at least two of antennas, in calculating a cyclic covariance matrix on a first moment, and on a second moment, of a spectral correlation of the digital signals acquired, and in detecting peaks of spectral correlation by comparing a likelihood ratio with a detection threshold determined statistically. The invention is applicable notably to digital radioelectric signals emitted by a satellite.
