Interferometric baseline performance estimations for multistatic synthetic aperture radar configurations derived from GRACE GPS observations

, 2006
Recent studies have demonstrated the usefulness of global positioning system (GPS) receivers for relative positioning of formation-flying satellites using dual-frequency carrier-phase observations. The accurate determination of distances or baselines

Internal Wave Characteristics in the Andaman Sea: New Insights From SWOT Observations

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract High‐resolution, repeat‐pass Sea Surface Height Anomaly (SSHA) observations from the Surface Water and Ocean Topography (SWOT) satellite are used to investigate Internal Solitary Waves (ISW) in the Andaman Sea over a one‐year period starting in July 2023. SWOT captured surface signatures of high‐amplitude ISW, with SSHA exceeding 20 cm.

Predicting structural disasters with Radar interferometry

IABSE Reports, 2015
<p>Radar interferometry is a technique which can observe the earth’s surface during day and night time. It makes uses of thousands of pulses per second that are transmitted by satellites and reflected by the surface of, for instance, structures.

A First Attempt at Reconstructing FengYun‐4B Stratified Precipitable Water Using GNSS

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Layer Precipitable Water (LPW) characterizes the vertical structure of atmospheric moisture and is essential for accurate weather forecasts. China's FY‐4B satellite delivers near‐real‐time LPW products, but is constrained by large uncertainties.

A First Look at the Snow/Ice Penetration Effect of SWOT Observations on Water Level of Global Glacial Lakes

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The Surface Water and Ocean Topography (SWOT) mission promises quasi‐global monitoring of glacial lakes, yet the elevation difference arising from its Ka‐band radar penetrating lake snow/ice cover remains unquantified. This poses a challenge to assessing their level changes.

Foliage penetration effect on polarimetric SAR interferometry observation of forest [PDF]

, 2008
The capability of electromagnetic waves to penetrate trough foliage (FOLPEN), combined with the potentialities of the polarimetric SAR interferometry (POL-InSAR) are demonstrated to be valid instruments for the investigation of forest characteristics and

Multibaseline Polarimetric SAR Interferometry Coherence Optimization

, 2008
This letter analyzes different approaches for polarimetric optimization of multibaseline (MB) interferometric coherences. Two general methods are developed to simultaneously optimize coherences for more than two data sets. The first method provides every
