【 摘 要 】

The paper presents the algorithm of locating harmonic microseismic signals using phases of the signals and spectral transformations. Different spectral transformations are considered and their properties required for the set problem solving are identified. The determination of the harmonic signals' location is exemplified using synthetic data.
