Abstract:In the literature, stationary phase analysis of Kirchhoff-type demigrated fields is carried out mainly under the following two conditions: (1) The considered isochrone and the target reflector are tangential to each other; (2) The spatial duration of the wavelet of the depthmigrated image is short. For the isochrones that are not tangential to the target reflector and for the depth-migrated images that have a large spatial duration, the published stationary phase equation for the demigrated field will become i… Show more
