Special Issue Information

Dear Colleagues,

InSAR technology has been widely applied to digital elevation model (DEM) generation and geo-hazard deformation analysis. As an ill-posed problem, the accuracy of the InSAR product is sensitive to the selection of parameters and processing approaches with rapid ground deformation or topographic changes. It requires that the InSAR signal processing practitioners be well-experienced, which is unfavorable to the generalization and commercialization of InSAR. Today, deep learning provides a new data-driven framework for accumulating experience. Moreover, deep learning techniques and a flood of valuable data coming from different InSAR sensors allow us to enable the learning-based “data model” outside of the traditional ones, which will act as a new discovery agent to investigate and explore previously intractable or inaccessible problems. This Special Issue aims to invite contributions on the latest developments and advances of the learning algorithms and frameworks on InSAR signal processing and applications.

Topics To Be Covered

  • Learning-based approaches on InSAR signal processing chain, e.g., denoising and phase unwrapping
  • Learning algorithms and models of InSAR data for Earth remote sensing (supervised/weakly supervised/unsupervised)
  • Fusion framework of the datasets from disparate InSAR systems
  • A comparative study of the existing learning approaches of InSAR datasets

With the development of imaging and space-borne satellite technology, a growing number of multipolarized SAR imageries have been implemented for object detection. However, most of the existing public SAR ship datasets are grayscale images under single polarization mode. To make full use of the polarization characteristics of multipolarized SAR, a dual-polarimetric SAR dataset specifically used for ship detection is presented in this paper (DSSDD). For construction, 50 dual-polarimetric Sentinel-1 SAR images were cropped into 1236 image slices with the size of 256 × 256 pixels. The variances and covariance of both VV and VH polarization were fused into R,G,B channels of the pseudo-color image. Each ship was labeled with both a rotatable bounding box (RBox) and a horizontal bounding box (BBox). Apart from 8-bit pseudo-color images, DSSDD also provides 16-bit complex data for readers. Two prevalent object detectors R3Det and Yolo-v4 were implemented on DSSDD to establish the baselines of the detectors with the RBox and BBox respectively. Furthermore, we proposed a weakly supervised ship detection method based on anomaly detection via advanced memory-augmented autoencoder (MemAE), which can significantly remove false alarms generated by the two-parameter CFAR algorithm applied upon our dual-polarimetric dataset. The proposed advanced MemAE method has the advantages of a lower annotation workload, high efficiency, good performance even compared with supervised methods, making it a promising direction for ship detection in dual-polarimetric SAR images. The dataset is available on github. Full article
