Improvement of non-linear chirp-scaling algorithm for highly squint bistatic SAR data focusing

open access: yesThe Journal of Engineering, 2019
Bistatic synthetic aperture radar (SAR) has specific advantages, e.g. weak targets detecting, reducing system vulnerability, and anti-interference with low cost and flexible working modes.

Bi- and Multistatic SAR: Potentials and Challenges

open access: yes, 2004
Bi- and multistatic synthetic aperture radar (SAR) operates with distinct transmit and receive antennas which are mounted on separate platforms. Such a spatial separation has several operational advantages which will increase the capability, reliability ...

A Fast Back Projection Algorithm for Spotlight Mode Bi-SAR Imaging

open access: yesLeida xuebao, 2013
A Fast Back Projection (FBP) algorithm for spotlight mode Bistatic Synthetic Aperture Radar (Bi-SAR) was presented. Sync channel signal from land receiver was taken as matched filter for echo signal in the phase of range compression, and the secondary ...

Bistatic synthetic aperture radar using GNSS as transmitters of opportunity [PDF]

open access: yes, 2012
The thesis summarizes the research on the feasibility investigation of Space-Surface (i.e. a spaceborne transmitter and an airborne receiver) Bistatic Synthetic Aperture Radar (SSBSAR)with a Global Navigation Satellite System (GNSS) which is used as a ...

Relativistic Effects in Bistatic SAR Processing and System Synchronization

open access: yes, 2012
This paper addresses relativistic effects in bistatic and multistatic SAR systems and missions. It is shown that the use of different reference frames for bistatic SAR processing and bistatic radar synchronization is prone to nota-ble phase and time ...

Interferometric baseline performance estimations for multistatic synthetic aperture radar configurations derived from GRACE GPS observations

open access: yes, 2006
Recent studies have demonstrated the usefulness of global positioning system (GPS) receivers for relative positioning of formation-flying satellites using dual-frequency carrier-phase observations. The accurate determination of distances or baselines

Efficient Time-Domain Focussing for General Bistatic SAR Configurations: Bistatic Fast Factorised Backprojection

open access: yes, 2010
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.

Performance Prediction and Verification for the Synchronization Link of TanDEM-X

open access: yes, 2007
Bistatic Synthetic Aperture Radar (SAR) systems have a high potential for scientific, commercial and security applications. One of the benefits is the possibility to generate digital elevation models using bistatic interferometry.

New processing approach and results for bistatic TerraSAR-X/F-SAR spaceborne-airborne experiments

open access: yes, 2009
Following the success of the first bistatic spaceborne-airborne experiment between TerraSAR-X and FSAR carried out in November 2007, DLR has performed a second bistatic experiment in July 2008 with new challenging acquisitions.
