Because of its agility, flexibility, and accuracy, airborne repeat-pass Interferometric Synthetic Aperture Radar (InSAR) is capable of overcoming the disadvantages of a long revisit time and a low resolution in space-borne SAR interferometry and plays an irreplaceable role in monitoring the deformation of landslides, volcanoes, earthquakes, and so on. In this paper, the history and the worldwide status of the technology of airborne repeat-pass SAR interferometry are reviewed in detail. Then, an analysis of the accuracy of this technology is presented, its key problems in practice are stated, and the related researches in this field are introduced comprehensively. The development trends and the prospects of this technology are also described in this paper. Finally, it is pointed that several issues still need to be studied further for accurate parameter inversion.
