Oceanographic applications of spaceborne bistatic SAR

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
This work presents an analysis of the attainable performance of a bistatic SAR for oceanographic applications, such as the determination of sea state parameters and the reconstruction of the sea wave spectrum. The analysis has been developed with regard to the spaceborne bistatic SAR of the BISSAT mission.

On the Existence of Coverage and Integration Time Regimes in Bistatic SAR Configurations

IEEE Geoscience and Remote Sensing Letters, 2007
Bistatic synthetic aperture radar (SAR) is an extension of traditional monostatic SAR, which increases the flexibility in designing SAR missions. We describe a scheme for the computation of integration time and azimuth coverage of bistatic SARs based on ...

Experimental results with bistatic SAR tomography

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
This paper gives a quick overview of inversion methods for bistatic tomographic processing. The methods are tested over simulated and real data. The real data has been acquired from a set of indoor experiments carried out in the Radiation Laboratory (RadLab), at the University of Michigan.

Low frequency bistatic SAR measurements

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Airborne bistatic SAR data have been collected at VHF- and UHF-band to investigate clutter suppression in forested and urban areas. The synchronization between the SAR systems is accomplished using the 1-PPS signal provided by the GPS system. The same signal is also used as input to a disciplined 10 MHz master oscillator integrated in both radar ...

Bistatic SAR: Forecasting Spatial Resolution

IEEE Transactions on Aerospace and Electronic Systems, 2019
This paper derives closed-form expressions for bistatic synthetic aperture radar (SAR) spatial resolution of a generalized system from the $k$ -space or the wavenumber domain. These spatial resolution equations have not previously appeared in the literature.

Performance Simulator for Bistatic SAR Missions

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
This paper presents a Synthetic Aperture Radar (SAR) simulator designed to assess the performance of bi-static SAR missions. It is a modular software able to simulate realistic SAR data (including injection of the system non-idealities), to estimate the SAR performance at radiometric and interferometric level.

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.

Fundamentals of Bistatic SAR

2017
Bistatic SAR (BiSAR) has been developing for 40 years, and it is still a topic of much discussion in the field of radar. BiSAR is a SAR system whose transmitter and receiver are spatially separated. This separation improves the system’s capability, reliability and flexibility, making it a promising and useful supplement to a classical monostatic SAR ...

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
