Passive Bistatic Radar

2014
Abstract Passive bistatic radar (PBR) is the name given to a bistatic radar that makes use of emissions from broadcast, communications or radionavigation transmitters rather than a dedicated, co-operative radar transmitter. Such systems have a number of potential advantages. The receiver is passive and so potentially undetectable.

Bistatic Scattering From Anisotropic Rough Surfaces via a Closed-Form Two-Scale Model

IEEE Transactions on Geoscience and Remote Sensing, 2021
Bistatic radars have been a topic of increasing interest in recent years, thanks to the introduction of new bistatic (and multistatic) configurations, including those based on the opportunistic exploitation of global navigation satellite systems (GNSSs).

Focusing the L-Band Spaceborne Bistatic SAR Mission Data Using a Modified RD Algorithm

IEEE Transactions on Geoscience and Remote Sensing, 2020
LuTan-1 [(LT-1), i.e., TwinSAR-L] mission is an innovative spaceborne bistatic synthetic-aperture radar (BiSAR) mission focusing mainly on differential interferometry, which will be launched in 2020.

Bistatic Coherent Scattering From Rough Soils With Application to GNSS Reflectometry

IEEE Transactions on Geoscience and Remote Sensing, 2020
We present and discuss an electromagnetic model for the description of the coherent scattering from bare soils illuminated by a radar system under arbitrary bistatic geometries.

Optimal Polarization in Bistatic Scattering

SIAM Journal on Applied Mathematics, 1989
The authors obtain basic properties of optimal polarization in bistatic scattering. The paper describes two alternative methods, which are simple extension of those of \textit{C. Graves} [Radar polarization power scattering matrix. Proc. IRE, 248-252 (1956)] and \textit{E. Kennaugh} [The effects of polarization on echo characteristics. Ohio State Univ.

Passive bistatic radar (PBR) demonstrator

IET International Conference on Radar Systems 2007, 2007
We present a system characterisation of a passive bistatic radar (PBR). The system under investigation exploits 'illuminators of opportunity', which in this case are commercial, non-cooperative, VHF FM broadcast transmissions. The paper demonstrates the detection of large passenger-jet aircraft over central London.

Bistatic model of ocean scattering

IEEE Transactions on Antennas and Propagation, 1998
An analytical closed-form model is derived for the average power echo received by a bistatic altimeter from an oceanic surface at a frequency high enough for the Kirchhoff scattering mechanism to be dominant over the Bragg resonance one. The asymmetric behavior of the sea waves is taken into account, modeling the surface height as a non-Gaussian ...

Error Analysis of Bistatic SAR Imaging and Stereoscopy Bistatic SAR

IEEE Transactions on Geoscience and Remote Sensing, 2013
The flexible geometry configuration of the bistatic synthetic aperture radar (SAR) has many advantages. However, it causes serious measurement error in the bistatic SAR system, which degrades the quality of the SAR images and the precision of the digital elevation model (DEM) obtained using stereoscopy bistatic SAR.

Effect of bistatic angle on spread of bistatic BRAGG lines

International Conference on Automatic Control and Artificial Intelligence (ACAI 2012), 2012
For a bistatic HF radar, the bistatic angle over a clutter cell is a variable. This will cause the spread of the Bragg lines. A new analytical method is proposed to investigate the effect of the bistatic angle on this kind of spectrum spread: both the receive beam width and range resolution are taken into account together, then the Bragg lines width is

Resolution analysis of bistatic SAR

SPIE Proceedings, 2011
In this paper, we analyze the resolution of bistatic synthetic aperture radar (BISAR) imaging for stationary objects. In particular, we analyze the resolution of images reconstructed by the method of a filtered backprojection inversion, an inversion method which is derived from a scalar wave equation model. In this context we are able to account for
