Bistatic inverse synthetic aperture radar imaging
IEEE International Radar Conference, 2005., 2005The use of a monostatic radar configuration limits the ability of an inverse synthetic aperture radar (ISAR) system to image targets in certain geometries. By employing bistatic geometries this limitation may be overcome. Bistatic radar systems will pay a great role in the coming decade since a large number of radar missions are being foreseen.

Vehicleborne bistatic synthetic aperture radar imaging
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007A complete vehicleborne Bistatic Synthetic Aperture Radar (SAR) imaging experiment is presented in this paper. Some new technologies were used to solve synchronization problems. An algorithm named the Glide Window Echo CFAR was used to realize time synchronization and collect the echo.

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.

Focusing bistatic synthetic aperture radar using dip move out
IEEE Transactions on Geoscience and Remote Sensing, 2004The appearance of new synthetic aperture radar (SAR) acquisition techniques based on opportunity sources enhances interest in bistatic geometries. In seismic data acquisition, each source is currently accompanied by up to 10 000 receivers, and in the last two decades, the bistatic geometry has been carefully studied by scores of authors.

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 ...

The Processing Of Synchronization In Bistatic Synthetic Aperture Radar
2020 21st International Radar Symposium (IRS), 2020The time and phase synchronization are the important issues that must be addressed for bistatic synthetic aperture radar (BiSAR). The processing of synchronization is discussed in the paper. First, the synchronization scheme of LuTan-1 system is introduced in detail.

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 ...

Bistatic Synthetic Aperture Radar imagery simulation of sea surface
2010 International Conference on Microwave and Millimeter Wave Technology, 2010A bistatic Synthetic Aperture Radar (Bis-SAR) imagery simulation of an extended sea surface is presented which is based on a facet scattering model. A semi-deterministic approach is developed to calculate high frequency bistatic raw data from the model of large sea surface.
