Spaceborne bistatic Synthetic Aperture Radar for remote sensing applications
International Journal of Remote Sensing, 2000This paper presents a performance analysis of spaceborne bistatic Synthetic Aperture Radar (SAR) for Earth observation. Since a bistatic system requires the simultaneous use of two spatially separated antennae, this paper refers to the European Space Agency ENVISAT-1 ASAR as the master mission, i.e.

Moving Target Artifacts in Bistatic Synthetic Aperture Radar Images
IEEE Transactions on Computational Imaging, 2015Synthetic aperture radar (SAR) imaging methods are designed to image stationary scenes. Moving targets appear smeared and misplaced in reconstructed SAR images. This paper presents a theory to quantitatively analyze and predict positioning errors due to moving targets in bistatic SAR imagery.

Bistatic Synthetic-Aperture Radar Imaging of Rotating Objects
IEEE Transactions on Aerospace and Electronic Systems, 1982The imaging properties of a focused radar aperture synthesized by object rotation are considered. The ring-shaped aperture synthesized by the object rotation can provide high-resolution two-dimensional imaging using only monochromatic irradiation. The case of monochromatic irradiation is extended to the polychromatic case and to equivalent bistatic ...

Parametric scattering models for bistatic synthetic aperture radar
2008 IEEE Radar Conference, 2008Parametric scattering center models match to radar scene attributes, aiding in automatic target recognition (ATR) and scene visualization. In this paper, we develop parametric models of canonical shapes for bistatic synthetic aperture radar (SAR).We generalize geometric theory of diffraction solutions for scattering mechanisms in a plane to develop ...

An Advanced Non-Interrupted Synchronization Scheme for Bistatic Synthetic Aperture Radar
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019The phase synchronization is one of the key issues to be addressed for the bistatic synthetic aperture radar system. In this paper, an advanced non-interrupted phase synchronization scheme is proposed. Both satellites are equipped with four synchronization antennas for a mutual exchange of synchronization pulses, which are transmitted rightly after the

Fundamentals of Bistatic Synthetic Aperture Radar
2008This chapter gives an overview of the main issues of BSAR for airborne and spaceborne remote sensing applications. A brief review of the state-of-the-art in bistatic radar is made, showing both limitations in availability of bistatic systems and data and the great interest for their potentialities, and then BSAR geometry is presented.

GEO-UAV bistatic circular synthetic aperture radar: Concepts and technologies
2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016This paper proposed an innovative bistatic radar system, named as GEO-UAV bistatic circular synthetic aperture radar (BCSAR). In GEO-UAV BCSAR, the geostationary satellite serves as the transmitter, while the receiver is mounted on the UAV platform moving along a circular trajectory.

Remote sensing satellite formation for bistatic synthetic aperture radar observation
SPIE Proceedings, 2001In recent years the Italian Space Agency has been proceeding to the definition and launch of small missions. In this ambit, the BISSAT mission was proposed and selected along with five other missions for a competitive Phase A study. BISSAT mission concept consists in flying a passive SAR on board a small satellite, which observes the area illuminated ...
