“…The InSAR system [12] can obtain elevation information, and interferometric phase [13] is sensitive to terrain and platform attitude, so InSAR system is still available with rugged terrains. Interferometric phase is long‐term stable, and generation of real‐time interferograms is feasible, but it is difficult to obtain real‐time terrain digital elevation models (DEMs).…”
