Abstract

Height reconstruction error in InSAR system can be divided into fixed and variable height error. Fixed height error can be eliminated by the differential sensitivity equations, so only the system parameter errors, which can cause the variable height error, are involved into the procedure of iterating. To take advantage of these features, the differential interferometric calibration algorithm is proposed to reconstruct the height terrain. The simulation results show that the algorithm can achieve accurate height reconstruction.
