Multi-dimensional Imaging with MD-JoSAR Mission in China: Challenges and Opportunities

Abstract:
With the advancement of synthetic aperture radar (SAR) technology, the joint observation of multiple dimensions, including polarization, frequency, angle, and time, has emerged as a significant trend in SAR development. Multidimensional SAR imaging holds great potential for various fields, such as remote sensing, geology, agriculture, and defense, as it enables accurate and detailed imaging of complex structures. Extracting information from multiple dimensions offers valuable insights and enhances the understanding and management of natural resources, geological hazards, and security threats. This paper provides an overview of the capabilities of the airborne multidimensional joint observation SAR (MD-JoSAR) observation system, and presents a summary of its technical features. Additionally, the preliminary experimental results of three new multi-dimensional SAR observations, namely, the multi-band multi-aspect full polarization spectrum, multi-aspect three-dimensional structure, and multitemporal coherence change detection, are analyzed to validate the system's multi-dimensional observation capabilities.
