Zusammenfassung:An InSAR image registration method based on a wave path difference sequence is disclosed. The invention relates to the InSAR image registration method based on the wave path difference sequence. By using an existing registration method based on an image characteristic, the process of extracting the image characteristic is complex and the operand of a whole registration process is increased. In theinvention, the above problems are solved. The method comprises the following steps of 1, imaging any ground scene by an InSAR platform system and calculating the ground width of an imaging scene; 2,calculating the wave path difference sequences of a ground point target in the imaging scene to the two antennas of the platform; 3, rounding the wave path difference sequences, acquiring a new sequence, and calculating the mode and the mean value of the new sequence; 4, calculating the difference of the mode and the mean value and taking as the offset amount of distance registration; and 5, takethe image formed by the ant
