The statistically optimal space-time signal processing algorithm for the point sources selection of noise signals is considered. The representation of the space-time covariance observation matrix as a set of matrices obtained from the averaged signals of the multipoint delay lines of the adaptive antenna array receiving channels is used as the algorithm basis. This made it possible to construct the angular position estimates of the sources on the eigenvalue analysis. The signal processing in this case includes the space-time covariance matrix estimation by the signals of receiving channels, the eigenvalues calculation of the space-time covariance matrix, the ranking calculation of eigenvalues, the corresponding coefficients estimation of the amplifier matrix. The gain in the sensitivity in relation to the classical processing method depends substantially on the tolerance observation interval during which the signals are received.
