Reviews of Geophysics, Volume 63, Issue 4, December 2025.Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...

Geophysical Research Letters, Volume 52, Issue 22, 28 November 2025.Abstract During the T119 bistatic radar (BSR) experiment, the Cassini spacecraft observed a collection of lakes in Titan's Northern Lake District. Specular reflections from liquid surfaces were clearly detected at X‐band ground‐based station DSS‐43 (Canberra), spaced out by sudden drops of power in correspondence to solid terrains.

An LFM-Based Semiblind Synchronization Method for Bistatic Radar Imaging
IEEE Journal of Selected Topics in Applied Earth Observations and Remote SensingBistatic radar provides an additional degree of freedom in the observing geometry for imaging by using a spatially separated transmitter and receiver. This capability allows the capture of scattering phenomena at various bistatic sensing angles, which ...

Target Coordinates Estimation by Passive Radar with a Single non-Cooperative Transmitter and a Single Receiver [PDF]
Journal of Communications Software and Systems, 2020 Passive radar is a bistatic radar that detects and tracks targets by processing reflections from non-cooperative transmitters. Due to the bistatic geometry for this radar, a target can be localized in Cartesian coordinates by using one of the following ...

Large‐Scale Topographic Changes at Erupting Volcanoes Measured by the TanDEM‐X Digital Change Map
Earth and Space Science, Volume 12, Issue 11, November 2025.Abstract Volcanic eruptions cause large‐scale topographic changes, through the emplacement of lava flows and lava domes, the formation of craters and calderas, and thick ash and pyroclastic deposits. Here we analyze the TanDEM‐X Digital Change Map (DCM), which compares the DEM produced during 2010–2015 with satellite acquisitions collected in 2016–2022.
