Recent Advances in Multi-Platform SAR for Surface and Structural Deformation Monitoring

Dear Colleagues,

Recent developments in SAR platforms, including satellites, aircraft, UAVs, and ground-based radar systems, have greatly improved to measure displacement with high spatial and temporal resolution. These advanced SAR systems complement one another and enable detailed investigations across a range of natural and anthropogenic environments.

Surface deformation is closely linked to hazards such as earthquakes, volcanic activity, ground subsidence, and landslides and is important in assessing the stability of urban infrastructure. Accurate and continuous monitoring of surface displacement are essential for understanding its mechanisms and supporting disaster mitigation and early warning. Interferometric radar techniques now play a key role in providing reliable deformation measurements.

This Special Issue welcomes studies on methodological advances, improved processing techniques, and practical applications for high-precision deformation monitoring. Topics include InSAR time-series analysis, multi-platform interferometry, UAV-SAR, ground-based radar measurements, and calibration and validation approaches. We also encourage contributions related to geohazards, infrastructure stability, and environmental deformation.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Remote Sensing is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
