Special Issue Information

Dear Colleagues,

With the continuous advancement of high-resolution Polarimetric Synthetic Aperture Radar (PolSAR) technology, PolSAR data have been used to perform ongoing Earth observation and analysis in various fields, such as agriculture, forestry, urban monitoring, marine observation, and disaster assessment. Through PolSAR data, researchers can accurately identify crop types, monitor forest health, analyze urban expansion trends, detect ocean surface characteristics, and assess the impact of natural disasters. These applications not only enhance our understanding of the Earth's environment but also provide powerful technical support for resource management, environmental protection, and disaster emergency response.

This Special Issue aims to highlight innovative PolSAR imaging applications and techniques, encompassing a broad range of technical principles and practical applications. It includes topics such as Multitemporal SAR/PolSAR, Change Detection, Target Decomposition, PolInSAR and Land Coverage Classification to facilitate a deeper understanding of the challenges associated with PolSAR image interpretation. Additionally, this Special Issue welcomes the submission of papers related to other aspects of SAR image interpretation, such as target detection and automatic target recognition.

We welcome original research articles, reviews, and case studies whose scope includes, but is not limited to, the following topics:

  • Analysis of Multitemporal SAR/PolSAR data.
  • Polarimetric Target Decomposition.
  • Novel algorithms for change detection and analysis with PolSAR image.
  • Land Coverage Mapping and Classification based on remote sensing image.
  • Application of Artificial Intelligence Techniques in PolSAR image interpretation.
  • Inversion with PolInSAR technology.

Dual polarimetric SAR is capable of reflecting the biophysical and geometrical information of terrain with open access data availability. When it is combined with time-series observations, it can effectively capture the dynamic evolution of scattering characteristics of crops in different growth cycles. However, the actual planting of crops often shows spatial dispersion, and the same crop may be dispersed in different plots, which fails to adequately consider the correlation information between dispersed plots of the same crop in spatial distribution. This study proposed a crop classification method based on multi-temporal dual polarimetric data, which considered the utilization of information between near and far spatial plots, by employing superpixel segmentation and a HyperGraph neural network, respectively. Firstly, the method utilized the dual polarimetric covariance matrix of multi-temporal data to perform superpixel segmentation on neighboring pixels, so that the segmented superpixel blocks were highly compatible with the actual plot shapes from a long-term period perspective. Then, a HyperGraph adjacency matrix was constructed, and a HyperGraph neural network (HGNN) was utilized to better learn the features of plots of the same crop that are distributed far from each other. The method fully utilizes the three dimensions of time, polarization and space information, which complement each other so as to effectively realize high-precision crop classification. The Sentinel-1 experimental results show that, under the optimal parameter settings, the classified accuracy of combined temporal superpixel scattering features using the HGNN was obviously improved, considering the near and far distance spatial correlations of crop types.
