Performance and Applications of N-SAR-SG

N-SAR-SG is a Chinese multi-functional integrated experimental airborne SAR system developed by Nanjing Research Institute of Electronic Technology. It supports up to 6 frequency bands (P, L, S, C, X and Ku), which can operate with multi-band, -polarimetry, -channel, -mode, and - baseline simultaneously. To certificate the systems, as well as new concepts, new applications, and new technologies in microwave remote sensing, we carried out a series of flight experiments. Based on the dataset, some interesting processing results are obtained such as dual band tree height precise inversion, ground elevation measurement enhancement with the combination of cross-track and along-track interferometry, terrain Classification based on joint frequency-interference-polarization SAR information. These novel experiments not only prove the progressiveness of N-SAR-SG, but also inspire some potential development directions of SAR techniques.
