The invention provides a building tilt monitoring method based on the InSAR technology. The invention relates to the synthetic aperture radar interferometry technology (InSAR), more particularly to anInSAR tilt monitoring technology for buildings and high-rise structures. The method comprises: step one, acquiring a differential interferogram set using the differential interferometry technique (DINSAR); step two, with the time sequence InSAR technique, acquiring patial position and deformation information of a building surface monitoring point set; and step three, calculating a tilt directionand tilt degree of each of the buildings and high-rise structures by using the InSAR monitoring result and satellite parameter information. According to the method, the spatial position and deformation information of the building surface monitoring points is obtained based on the InSAR technology and the tilt direction and tilt degree of the building are obtained by combining the satellite image parameters and orbit data.
