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.

Bistatic Synthetic Aperture Radar Imaging: Theory, Simulations, and Validations
IEEE Transactions on Antennas and Propagation, 2006A three-dimensional "full-polarized" model for arbitrary transmitter, receiver and target motions in bistatic synthetic aperture radar configurations is proposed. Qualitative validation of this model is presented through comparison with existing results and quantitative validation is obtained from proposed general analytical resolution equations.

Spaceborne Bistatic Synthetic Aperture Radar
2008In order to maintain adequate swath overlap along the orbit, BSAR missions require careful selection of orbits and pointing which must also take into account system-level issues, for instance: impacts on transmitting/receiving radar mission, requirements on bistatic payload/bus, lifetime.

Ground-Based Bistatic Polarimetric Interferometric Synthetic Aperture Radar System
IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019A novel ground-based bistatic polarimetric synthetic aperture radar (SAR) system using an Optical Electric Field Sensor (OEFS) as the receiver was developed for environmental studies. Fundamental experiments were carried out with a trihedral corner reflector (CR) as a target, showing the polarimetric capability of the system.

Convolution-backprojection image reconstruction for bistatic synthetic aperture radar
IEEE International Symposium on Circuits and Systems,, 1989The algorithm presented accounts for the elliptical nature of the wavefronts over the ground patch (resulting in elliptical-arc projections) and is based on the convolution-backprojection (CBP) algorithm of computer tomography. Essentially, three changes were made to the CBP algorithm.

Bistatic Synthetic Aperture Radar Timing Synchronization Based on DSSS
2006 CIE International Conference on Radar, 2006Timing synchronization is one of the key techniques for Bistatic Synthetic Aperture Radar (BiSAR). This paper addresses the timing synchronization methods for BiSAR systems. One-way timing configuration is proposed first, which is based on direct spread spectrum sequence acquisition and tracking techniques.

Field test of bistatic forward-looking synthetic aperture radar
IEEE International Radar Conference, 2005., 2005Monostatic radar systems reach their limits if a two-dimensional resolution is desired for a forward-looking geometry. Bistatic systems offer an alternative to handle this problem if the transmitter operates as a separated illuminator while the receiver is arranged in a forward-looking mode.

Space-surface bistatic synthetic aperture radar - prospective and problems
RADAR 2002, 2002The paper introduced a feasibility analysis of a synthetic aperture radar (SAR) with novel architecture. Two essential peculiarities are discussed: the system configuration with a moving transmitter when the receiver is stationary and noncooperative transmitters utilization for the system. The system is named space-surface BSAR or S-SBSAR.
