Surface Deformation Monitoring in Coal Mine Area Based on PSI

IEEE Access, 2019
It is difficult to get robust deformation results using conventional differential interferometric synthetic aperture radar (D-InSAR) method, due to the limitation of the phase measurement error, baseline error, and atmospheric delay in synthetic aperture

The TanDEM-X Mission Design and Data Acquisition Plan [PDF]

, 2006
The TanDEM-X mission comprises two fully active synthetic aperture radar Xband satellites, operating three years as a joint mission. The primary goal of this mission is the derivation of a high-precision global DEM according to HRTI level 3 quality. Also

Ground-based HF to VHF radar calibration by scattering off a stratospheric balloon [PDF]

Atmospheric Measurement Techniques
The knowledge of radar system properties is crucial for judging radar performance and correctly interpreting received raw and analysed data. The most critical part of that is the radiation pattern, which is often very difficult to measure for atmospheric/

Spaceborne Radar Technologies for Earth Remote Sensing [PDF]

, 2007
Synthetic Aperture Radar (SAR) is an indispensable source of information in earth observation since SAR is the only spaceborne sensor that has highresolution, all-weather and day-and-night imaging capability.

Polarimetric Optimisation in Radar Interferometry

, 1997
A general formation for vector wave interferometry is outlined and the optimisation of the phase coherence. In this way it is shown that wave polarisation effects play an important role in the extraction of information from radar ...

L’interferometria SAR satellitare per la misura delle deformazioni superficiali

GEOmedia, 2012
La tecnica interferometrica, basata  sull’elaborazione coerente della fase del ritorno del segnale radar dalla superficie terrestre, ha reso il telerilevamento radar uno strumento di analisi quantitativa in molteplici campi applicativi quali cartografia,

Synthetic Interferometry Exploiting Radar Motions

The instantaneous velocity of any moving object can be decomposed into two orthogonal components with reference to the observing radar, namely radial velocity along the radar line of sight (LoS) and transversal velocity perpendicular to the LoS.
