A reweighted matrix completion algorithm for sparse inverse synthetic aperture radar imaging
IET Radar, Sonar & Navigation, 2023 Sparse inverse synthetic aperture radar (ISAR) imaging can be generally achieved by compressed sensing (CS) methods because sparse sampling disables the approach of conventional range Doppler. However, the CS‐based methods have to convert the matrix into

High Voltage, EarlyView.ABSTRACT Power lines in synthetic‐aperture radar (SAR) images are reflected as point signatures, which fluctuate annually in both the azimuth and range directions. A novel framework is proposed in this paper to evaluate the four‐dimensional dynamic status of power line sag using those point signatures in time‐series SAR images.

An Autofocus Technique for High-Resolution Inverse Synthetic Aperture Radar Imagery [PDF]
IEEE Transactions on Geoscience and Remote Sensing, 2014 For inverse synthetic aperture radar imagery, the inherent sparsity of the scatterers in the range-Doppler domain has been exploited to achieve a high-resolution range profile or Doppler spectrum. Prior to applying the sparse recovery technique, preprocessing procedures are performed for the minimization of the translational-motion-induced Doppler ...

Transactions in GIS, Volume 30, Issue 5, August 2026.ABSTRACT Transmission corridors are critical components of power delivery infrastructure, and their large‐area monitoring increasingly relies on national‐scale airborne lidar programs. This study presents an unsupervised, scalable framework for extracting transmission corridor structures (including conductors and supporting towers) from U.S. Geological

Advances in Synthetic Aperture Radar from a Wavenumber Perspective [PDF]
, 2017 This dissertation examines the wavenumber domain of Synthetic Aperture Radar (SAR) images. This domain is the inverse Fourier transform domain of a SAR image.

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.Abstract Unsustainable rates of groundwater (GW) depletion make GW management a priority. Effective GW management is hindered by the uncertainty in the predictions of aquifer models, but the increase of geodetic surface deformation data can improve aquifer characterization.

Synthesis of Inverse Synthetic Aperture Radar (ISAR) Using Matlab [PDF]
, 2021 High-resolution radar images can be achieved by employing synthetic aperture radar (SAR) or inverse synthetic aperture radar (ISAR) techniques. It can be shown that SAR and ISAR have the same underlying theory but different configuration.

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.Abstract We developed an innovative balloon‐borne observation system based on China's BeiDou sounding platform that integrates a three‐axis electric field sensor for in‐cloud measurements of thunderstorm electrification. On 13 May 2025, this system was deployed during a severe convective storm over Beijing. In combination with multisource observations,
