Abstract In this paper, a method for dynamic measurement of non-rigid baseline of dual-antenna InSAR is presented and discussed. In this scheme, the position and orientation of the antenna is obtained by using a CCD camera and a laser range finder together. In this paper, the research of principle and experiments are carried out. In the experiments, the movement of the antenna is created by some equipments, the tracks of which can be controlled accurately. The results of experiments show that the errors of position and attitude are less than 0.2mm and 70 arcseconds. The method is applicable to determine the baseline of dual-antenna dynamically.
