Radio echo sounding is an active remote-sensing method using electromagnetic wave penetration in a particular medium such as ice and permits the measurements of its thickness, the level of the bedrock...
Studies of the dynamics of the ionosphere and its related phenomena are mainly based on Doppler Drift measurements. The time variation (ionisation/recombination) of plasma density, thermospheric wind ...
Radar technology has for a long time used various systems that allow detection under high-resolution conditions, while emitting at the same time low peak power. Among these systems, transmitted pulse ...
Active remote sensing techniques can probe volcanic ash plumes, but their sensitivity at a given distance depends upon the sensor transmitted power, wavelength and polarization capability. Building on...
Radar data of non-specular meteor trails shows two clear and consistent features: (1) non– specular meteor trails are observed from a narrower altitude range than are head echoes and (2) an approxi...
Off-shore detection of tsunami waves is a critical component of an effective tsunami early warning system (TEWS). Even more critical is the off-shore detection of local tsunamis, namely tsunamis that ...
The aim of this work is to analyse the advantages and disadvantages of using the new X-band SAR data acquired by TerraSAR-X sensors for landslides mapping. This dataset has been processed using a Pers...
When targeting small amplitude surface deformation, using repeat orbit Interferometric Synthetic Aperture Radar (InSAR) observations can be plagued by propagation delays, some of which correlate with ...

Can We Calibrate Radar with Raingauges?
In order to identify the underground objects, we often use a Ground Penetrating Radar (GPR) from the point of reducing cost and time. But it is not a few cases that the pavement situation prevents fro...
When a meteoroid penetrates Earth’s atmosphere, it forms a high-density ionized plasma column immersed in the ionosphere between approximately 70 and 140 km altitude. High-power, large-aperture (HPL...
Subglacial bed conditions exert a signif i cant control on ice stream behavior and evolution, and can be characterized by determining bed roughness from FFT analysis of r adar-imaged basal reflector...
Despite decades of research, many questions remain about the global flux of meteoroids at Earth, their influence on the atmosphere, and their use as upper atmospheric diagnostics. We see high-power l...
Large-aperture radars detect the high-density plasma that forms in the vicinity of a meteoroid and moves approximately at its velocity; reflections from these plasmas are called head echoes. To deter...
We use interferometric synthetic aperture radar (InSAR) and broadband seismic waveform data to estimate source parameters of the 29 June 1992,Ms 5.4 Little Skull Mountain (LSM) earthquake. This event ...
