Multi‐Angle Bistatic Scattering Characteristics of Ground Targets Observed by GB‐SAR Experiment
This paper presents an experimental investigation of bistatic scattering characteristics using an outdoor ground‐based SAR system working in Ku‐band. Representative artificial and natural targets were measured and analysed to characterise their angular bistatic scattering responses and underlying scattering mechanisms.

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.

Performance Prediction and Verification for Bistatic SAR Synchronization Link [PDF]
Bistatic SAR systems have a high potential for scientific, commercial and security applications. One of the benefits is the possibility to generate highly accurate digital elevation models using bistatic interferometry.

Large‐Scale Topographic Changes at Erupting Volcanoes Measured by the TanDEM‐X Digital Change Map
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.

The Radiometric Measurement Quantity for SAR Images [PDF]
A Synthetic Aperture Radar (SAR) system measures among other quantities the terrain radar reflectivity. After image calibration, the pixel intensities are commonly expressed in terms of radar cross sections (for point targets) or as backscatter ...

Beam Footprint Detection and Tracking for Non-cooperative Bistatic SAR [PDF]
In non-cooperative bistatic synthetic aperture radar (SAR), the position of transmitter’s beam footprint should be detected and tracked in real-time to perform beam synchronization.

Abstract Lava tubes are subsurface conduits within a lava flow that feed its advance. Lava tube detection is important to understand lava flow dynamics and to mitigate geohazards. Here we use InSAR‐derived surface motion data, in combination with shortwave and thermal infrared imagery, to delineate a ∼14 km long lava tube system at Fernandina volcano ...

A Versatile Processing Chain for Experimental TanDEM-X Product Evaluation [PDF]
TanDEM-X is a high-resolution interferometric mission with the main goal of providing a global digital elevation model (DEM) of the Earth surface by means of single-pass X-band SAR interferometry.
