Abstract

Interferometric Synthetic Aperture Radar (InSAR) has become a research focus in airborne remote sensing systems. In order to improve the image quality, it is essential to apply accurate motion error compensation. In this paper, a high-precision Ring Laser Gyroscope (RLG) Position and Orientation System (POS) is developed, and it can offer time and space reference information for InSAR to compensate motion errors. The developed RLG POS was applied in airborne InSAR surveying and mapping system successfully. The airborne experiments show that height estimation sensitivity of InSAR compensated by RLG POS had been improved to 0.27m from 3m.
