A locally optimal algorithm for detecting weak low-frequency geophysical signals by the use of long-baseline laser interferometric gravitational antennas that operate in the free spectral range mode is considered. The likelihood ratio is derived using the estimate-correlation online processing of signals. The main element of the optimal detector in the Gaussian approximation is the realizable Wiener filter. A calculation formula for the signal-to-noise ratio is presented.
