Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus in which the position and the structure of an object in a medium can be detected with high accuracy and three- dimensionally without being affected largely by the size, shape, arrangement or the like of the object. SOLUTION: While the surface of a medium 1 is being moved, a wave signal 4 is radiated into the medium 1, and a reflected signal 5 from an object 2 is received. A three dimensional migration processing operation is performed to three dimensional vector data in which a position (x, y) on the surface of the medium 1 generated on the basis of the intensity of the reflected signal 5 and the reflection time (t) from the object 1 are set as coordinates (x, y, t) while a plurality of propagation speeds (v) which are supposed in advance are used as parameters. On the basis of its result, the representative value of every coordinate point is extracted. On the basis of the representative value, the long body candidate region of the object 2 is extracted.  The eigenvalue and the eigenvector of the variance-covariance matrix of a coordinate distribution are computed for every long body candidate region. A feature is extracted. A long body region is extracted. A discrete representative coordinate point and a representative propagation speed which are extracted in every long-body region are interpolated. Thereby, the distribution of the propagation speeds (v) is computed.
