Examining and processing method for underground buried object

Abstract

Abstract PURPOSE:To enable the obtaining of 3-D image information, by converting a 3-D array of reflection information into a 2-D data array to perform a synthetic opening processing. CONSTITUTION:A measuring input data in the (k)-th section and measuring input data in the (k+1)-th, (k+2)-th... sections parallel therewith are stored into matrixes of (i) lines (j) columns. These matrixes are linked two- dimensionally to prepare measuring matrixes and reference matrixes. Then, the measuring matrixes are delivered according to filter characteristic worked out from an envelope of each spectrum obtained by Fourier transformation of the reference matrixes to determine a matrix following synthesization by azimuth compression. Thus, a small matrix of a section unit in this matrix is arrayed three-dimensionally to perform a synthetic opening processing.
