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 ...

Bistatic parasitic SAR processor evaluation

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
Bistatic radar systems will pay a great role in the coming decade since a large number of radar missions are being foreseen. Using existing transmitters, formations of small passive receivers will enhance our capability to gather backscatter information from Earth.

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.

Bistatic FOPEN SAR

2011
This chapter has illustrated the advantages of a bistatic FOPEN SAR receiver working in concert with a tethered airborne GMTI radar illuminator. The potential for moderate resolution SAR operation is made possible by the shortrange, higher angular rate collection of a bistatic adjunct receiver.

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.

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.

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).

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.

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 Motion Compensation

2017
In this chapter, we focus on motion compensation in bistatic SAR. Motion compensation is an important and challenging issue for obtaining focused imagery from monostatic and bistatic SAR data. Due to fluctuations in the linear motion of the airborne SAR platform, the trace always deviates from an ideal straight line, which alters the regular phase ...
