The noncoherent complex periodic components of electric field time series in the boundary layer of Earth atmosphere are detected using ei-genvector and component analyser utility model. These components are localized at the frequencies equal to Moon tides\' frequencies and also at the combined frequencies of Moon and Solar tides. The detected components cannot be observed using the classical scheme of quadrature receiver, are modulated with 1/year multiplied frequencies and have active values equal to 0,6−1,1 V/m. The probability of false detection of components spectrally localized at Moon tides\' frequencies is not greater than 2,5-10−4. Four time series of vertical component of electric field are used. These are the data of Vladimir State University General and Applied Physics Department observation station (2003−2009); the data from stations in Dusheti (1976−1980), Voeikovo (1966−1995), V. Dubrovo (1974−1995). Data are processed using the analyser which computes the covariance matrix of the time series and it\'s eigenvectors and ei-genvalues. The eigenvector spectral analysis is more sensitive than classical spectral analysis of the time series. It is shown that Solar tide detection using classical quadrature scheme is possible but the Moon detection is odd - the mean and active values of the components decrease while analysis interval grows. The covariance matrices with dimension 1000 are used.
