Bistatic Synthetic Aperture Radar Imaging with Multi-GNSS Transmitters

IGARSS 2019 - 2019 IEEE International Geoscience and Remote Sensing Symposium, 2019
This paper presents bistatic synthetic aperture radar imaging preliminary results with multiGNSS transmitters and a fixed receiver. Geometry, ambiguity function and imaging algorithms are discussed to describe multi-GNSS BiSAR system. Simulation results are provided to demonstrate the performance improvement of the amount of information of a given ...

Bistatic Synthetic Aperture Radar imagery simulation of sea surface

2010 International Conference on Microwave and Millimeter Wave Technology, 2010
A 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.

Fundamentals of Bistatic Synthetic Aperture Radar

2008
This 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.

Spaceborne Bistatic Synthetic Aperture Radar

2008
In 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, 2019
A 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,, 1989
The 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, 2006
Timing 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., 2005
Monostatic 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, 2002
The 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.
