BISSAT: a bistatic SAR for Earth observation

IEEE International Geoscience and Remote Sensing Symposium, 2003
This paper summarizes scientific rationale and technical approach for a bistatic synthetic aperture radar (SAR) mission (BISSAT). The study has been funded by the Italian Space Agency for a competitive Phase-A study along with other five missions.

Performance analysis of bistatic SAR configurations

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
In this work we analyze the properties of integration time and azimuth coverage of bistatic SAR configurations. The kinematics of antennas is modelled as a motion at a constant velocity along a linear path. Orbits can be at different heights above the ground and have crossing projections on a horizontal plane.

Bistatic forward-looking SAR interferometry

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
An innovative interferometry configuration, imaging and digital elevation mode (DEM) generation method via bistatic forward-looking synthetic aperture radar (BiFLInSAR) is addressed in this paper. The analytical relationship expressions between the interferometric phase and the topographic height are derived. In addition, for the space-variant features

Attitude measurement errors in bistatic SAR

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Spatial synchronization and its importance in the imaging performance of bistatic synthetic aperture radar (SAR) systems has been explored in several recent studies. In this paper, attitude measurement errors (AME) are studied in the context of motion measurement errors (MME) since the transmitting and receiving antennas are attached to rigid bodies ...

Performance analysis for bistatic interferometric SAR configurations

IEEE International Geoscience and Remote Sensing Symposium, 2003
The results of an interferometric performance analysis for spaceborne parasitic SAR configurations are presented. The analysis includes errors due to limited SNR, block adaptive quantization, range and azimuth ambiguities, and geometric decorrelation for both flat surfaces and random volumes.

Study and Simulation on Bistatic SAR

2006 7th International Symposium on Antennas, Propagation & EM Theory, 2006
After introduction of system configuration of a multi-static SAR, essential principle and system performance is analyzed. By utilizing the Versatile SAR Simulation Model (VSARSM) simulation results are given, which sustained the theory.

Bistatic SAR: theory and simulation

2005 IEEE Antennas and Propagation Society International Symposium, 2005
At present, the most used configuration for synthetic aperture radar imaging is the monostatic one (i.e. transmitter and receiver use the same antenna). However, the multiplication of stealth radar targets and the need for more accurate observations imply new radar imaging configurations and processing developments.

Bistatic SAR image formation: A systematic approach

2014 IEEE Geoscience and Remote Sensing Symposium, 2014
In this paper, we provide a systematic overview on bistatic SAR image formation for arbitrary platform trajectories. Bistatic SAR may offer improved flexibility, performance and cost-efficiency if compared to monostatic SAR systems certainly at the expense of increased operational complexity.

Signal theoretical aspects of bistatic SAR

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
Bistatic SAR uses separated transmitter and re- ceiver flying on different platforms. This configuration is en- visaged to achieve benefits like the exploitation of additional information contained in the bistatic reflectivity of targets, reduced vulnerability in military systems or forward looking SAR imaging.

A Bistatic Point Target Reference Spectrum for General Bistatic SAR Processing

IEEE Geoscience and Remote Sensing Letters, 2008
A bistatic point target reference spectrum (BPTRS) based on Loffeld's bistatic formula (LBF) is derived in this letter. For LBF, the same contributions of the transmitter and receiver to the total azimuth modulation are assumed. This assumption results in the failure of LBF in the extreme configuration (i.e., spaceborne/airborne configuration).
