Passive Interfering Method for InSAR Based on Circularly Moving Strong Scatterers [PDF]

, 2015
A novel jamming method based on circularly moving strong scatterers is proposed. The jamming signal model is presented first, and the corresponding imaging results are derived through a range-Doppler algorithm.

Monitoring Bridge Vibrations via Spaceborne SAR Micro‐Doppler

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
The advent of Synthetic Aperture Radar (SAR) imaging has presented the possibility of remote monitoring of civil infrastructure on a large scale. Although well established for observing slow and long‐term phenomena, its application to vibration‐based structural health monitoring (SHM) remains relatively unexplored in the current literature.

Long‐Wavelength Ionospheric Compensation of InSAR Time‐Series Based on Global Ionosphere Maps

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Uncorrected long‐wavelength contributions remain a major limitation for interpreting InSAR time‐series over large areas (>100 km). Among them, the ionosphere can impact InSAR measurements across various timescales, potentially biasing secular velocity estimates.

A Network-Based Enhanced Spectral Diversity Approach for TOPS Time-Series Analysis [PDF]

, 2017
For multitemporal analysis of synthetic aperture radar (SAR) images acquired with a terrain observation by progressive scan (TOPS) mode, all acquisitions from a given satellite track must be coregistered to a reference coordinate system with accuracies ...

Peatland Surface Motion: Terminology, Measurement Approaches, Models and Insights From a Global Dataset

Ecohydrology, Volume 18, Issue 8, December 2025.
ABSTRACT The surface of peatlands is constantly in motion. While pristine mires are characterized by peat growth and reversible surface fluctuation, induced by water level fluctuations, drained peatlands show subsidence due to peat mineralization and physical compaction. Still, drained peatlands show smaller but marked short‐term surface fluctuation as

Synthetic Aperture Radar Interferometry Based on Vortex Electromagnetic Waves

IEEE Access, 2019
The vortex electromagnetic (EM) wave carrying orbital angular momentum (OAM) offers a new degree of freedom for synthetic aperture radar (SAR) imaging. Because vortex EM waves have helical wavefronts, the vortex EM wave-based SAR echo contains the three ...
