Research into a Consistency Cooperative Control Method for Attitude Orbit Coupling of SAR Satellite Formations under Communication Constraints

open access: yesAerospace, 2022
To solve the problem of communication delays and topology changes and achieve a high-precision formation configuration control index in the flight control of SAR (synthetic aperture radar) satellite formations, this paper studies the consistency ...

Geometric calibration of ERS satellite SAR images

open access: yesIEEE Transactions on Geoscience and Remote Sensing, 2001
Geometric calibration of the European Remote Sensing (ERS) Satellite synthetic aperture radar (SAR) slant range images is important in relation to mapping areas without ground reference points and also in relation to automated processing. The relevant SAR system parameters are discussed and calibrated by using the European Space Agency (ESA ...

Bistatic TerraSAR-X/F-SAR Spaceborne-Airborne SAR Experiment: Description, Data Processing and Results

open access: yes, 2010
We report about the first X-band spaceborne-airborne bistatic SAR experiment, using the German satellite TerraSAR-X as transmitter and DLR's new airborne radar system F-SAR as receiver. The data were acquired early November 2007.

Performance and processing of SAR satellite clusters [PDF]

open access: yesIGARSS 2000. IEEE 2000 International Geoscience and Remote Sensing Symposium. Taking the Pulse of the Planet: The Role of Remote Sensing in Managing the Environment. Proceedings (Cat. No.00CH37120), 2002
Spaceborne radar systems have been proposed that use the concept of "formation flying" satellites; a system wherein a cluster of small, individual satellites orbit the Earth while remaining in the same relative positions with respect to each other.
