A golden age for spaceborne SAR systems [PDF]

2014 20th International Conference on Microwaves, Radar and Wireless Communications (MIKON), 2014
Spaceborne Synthetic Aperture Radar (SAR) is the only imaging sensor technology that can provide all-weather, day-and-night and high-resolution images on a global scale. Today, SAR data are used for a multitude of applications ranging from geoscience and climate change research, environmental monitoring, 2-D and 3-D mapping, change detection, 4-D ...

A Concept for High Performance Reflector-Based Synthetic Aperture Radar [PDF]

, 2010
The success of current spaceborne Synthetic Aperture Radar (SAR) is boosting the performance requirement of next generation systems. In order to cope with the evolution of SAR, the design of the new systems will need to meet higher requirements for ...

Exploration of Advanced Bistatic SAR Experiments (in English)

Leida xuebao, 2014
This study concentrates on the results of several advanced hybrid bistatic SAR experiments. The hybrid bistatic configuration applies to the case in which the transmitter and receiver are mounted on different types of platforms, e.g., spaceborne/airborne,

Analysis of Low-Oversampled Staggered SAR Data

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020
The combination of SCan-On-REceive with continuous variation of the pulse repetition interval during transmission (staggered operation) is a viable option for the acquisition of high-resolution synthetic aperture radar (SAR) data over wide areas.

Efficient Time-Domain Image Formation with Precise Topography Accommodation for General Bistatic SAR Configurations [PDF]

, 2011
Due to the lack of an appropriate symmetry in the acquisition geometry, generalised bistatic SAR cannot benefit from the two main properties of low-to-moderate resolution monostatic SAR: azimuth-invariance and topography-insensitivity.

Estimation of the Deformation Temporal Evolution Using Airborne Differential SAR Interferometry [PDF]

, 2006
This paper presents airborne DInSAR results using a stack of 14 images, which were acquired by the Experimental SAR (E-SAR) system of the German Aerospace Center (DLR) during a time span of only three hours and fifteen minutes.

An Operational Processing Framework for Spaceborne SAR Formations

Remote Sensing, 2023
The paper proposes a flexible and efficient wavenumber domain processing scheme suited for close formations of low earth orbiting (LEO) synthetic aperture radar (SAR) sensors hosted on micro-satellites or CubeSats. Such systems aim to generate a high-resolution image by combining data acquired by each sensor with a low pulse repetition frequency (PRF).

TanDEM-X: A satellite formation for high-resolution SAR interferometry [PDF]

, 2007
TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurements) is an innovative spaceborne radar interferometer mission that was approved for full implementation by the German Space Agency in spring 2006. This paper gives an overview of the TanDEM-X
