A new attempt to detect hidden impact craters on the Earth surface and on ocean bottoms was made using high-tech computational methods. For detection and allocation of such structures, a fast two-dimensional wavelet transformation of the gridded gravimetric data was used. The method was tested on reliably known impact structures. The results obtained are promising. Known hidden circle structures are effectively detected and clearly distinguished in the selected areas
