Special Issue Information

Dear Colleagues,

Synthetic aperture radar (SAR) sensors are widely used in remote sensing applications for their all-day and all-weather imaging abilities. With the continuous emergence of new technologies, such as polarimetric SAR (PolSAR), interferometric SAR (InSAR), differential interferometric SAR (DInSAR), permanent scatterers SAR interferometry (PSInSAR), tomography SAR (TomoSAR), etc., the SAR opens a new window for us to understand the world, and its application has been extended to various fields, such as object monitoring, environmental protection, disaster management, urban planning, situational awareness, etc.

The massive amount of data obtained via a large number of satellites or aerial vehicles poses opportunities and challenges for the processing and application of SAR remote sensing data. How to interpret and utilize these data efficaciously and efficiently is a hot and difficult research topic in the related communities. In recent years, artificial intelligence (AI), especially deep learning (DL) techniques, has provided promising tools to overcome many challenging issues in the processing and utilizing of SAR data.

In this Special Issue, we are looking forward to receiving a variety of research contributions, whether they are theoretical or heuristic, that focus on the processing and/or utilizing of SAR data/images with AI techniques. We expect that new research will address practical problems with the help of advanced AI methods, and provide valuable insights into developing better SAR data processing techniques for a broad range of applications.

Original submissions are welcome. Suggested themes of interest include, but are not limited to, the following:

SAR Data Processing:

  • Advances in SAR data pre-processing, processing, or post-processing technologies.
  • Advances in InSAR, DInSAR, PSInSAR, TomoSAR technologies.
  • SAR image enhancement, augmentation, or generation.
  • Image fusion or translation between SAR and optical sensors.

SAR Data Applications:

  • Advances in SAR data/image based object detection, recognition, re-identification, classification, and tracking.
  • SAR data/image based urban, land, ocean, ice, soil, and vegetation applications.

Synthetic Aperture Radar (SAR) enables the acquisition of high-resolution imagery even under severe meteorological and illumination conditions. Its utility is evident across a spectrum of applications, particularly in automatic target recognition (ATR). Since SAR samples are often scarce in practical ATR applications, there is an urgent need to develop sample-efficient augmentation techniques to augment the SAR images. However, most of the existing generative approaches require an excessive amount of training samples for effective modeling of the SAR imaging characteristics. Additionally, they show limitations in augmenting the interesting target samples while maintaining image recognizability. In this study, we introduce an innovative single-sample image generation approach tailored to SAR data augmentation. To closely approximate the target distribution across both the spatial layout and local texture, a multi-level Generative Adversarial Network (GAN) architecture is constructed. It comprises three distinct GANs that independently model the structural, semantic, and texture patterns. Furthermore, we introduce multiple constraints including prior-regularized noise sampling and perceptual loss optimization to enhance the fidelity and stability of the generation process. Comparative evaluations against the state-of-the-art generative methods demonstrate the superior performance of the proposed method in terms of generation diversity, recognizability, and stability. In particular, its advantages over the baseline method are up to 0.2 and 0.22 in the SIFID and SSIM, respectively. It also exhibits stronger robustness in the generation of images across varying spatial sizes. Full article
