Two bistatic target signatures: the bistatic equations and the bistatic polarisation fork
12th International Conference on Microwaves and Radar. MIKON-98. Conference Proceedings (IEEE Cat. No.98EX195), 2002The object of this article is to present two mathematical supports which allow a better knowledge of the target in a bistatic polarimetric radar configuration. These aids are firstly the nine bistatic target equations which link together the new sixteen bistatic target parameters, and secondly the bistatic polarisation fork which visualises the sixteen

Bistatically equivalent monostatic approximation for bistatic ISAR
2013 IEEE Radar Conference (RadarCon13), 2013Bistatic Inverse Synthetic Aperture Radar has recently gained interest as bistatic and multistatic radar systems are becoming increasingly popular. A theoretical foundation has been laid that introduces the concept of Bistatically Equivalent Monostatic (BEM) configuration, which allows approximating a bistatic geometry with a monostatic one.

Error Analysis of Bistatic SAR Imaging and Stereoscopy Bistatic SAR
IEEE Transactions on Geoscience and Remote Sensing, 2013The 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.

ArcSAR is a particular implementation of GBSAR, which has been receiving increasing interest in the last years. The great advantage of ArcSAR is its capability to synthesize images at 360° with constant resolution in azimuth. Nevertheless ArcSAR has a critical limitation: it detects only the displacement component along the range direction.

Effect of bistatic angle on spread of bistatic BRAGG lines
International Conference on Automatic Control and Artificial Intelligence (ACAI 2012), 2012For 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

A Bistatic Point Target Reference Spectrum for General Bistatic SAR Processing
IEEE Geoscience and Remote Sensing Letters, 2008A bistatic point target reference spectrum (BPTRS) based on Loffeld's bistatic formula (LBF) is derived in this letter. For LBF, the same contributions of the transmitter and receiver to the total azimuth modulation are assumed. This assumption results in the failure of LBF in the extreme configuration (i.e., spaceborne/airborne configuration).

Study of Bistatic Angle's Impact on Imaging Performance in Bistatic RCS Measurement
2016 International Conference on Identification, Information and Knowledge in the Internet of Things (IIKI), 2016This paper introduces the imaging formula in bistatic radar cross section (RCS) measurement at first. Then the bistatic angle’s impact on imaging performance and the features of two typical bistatic RCS measurement modes are explored based on the shape of the corresponding Fourier transform spectrum domain (k-space).

SPIE Proceedings, 2014
The problems of simulation of bistatic SAR raw data and focusing are studied. A discrete target simulator is described. The simulator introduces the scene topography and compute the integration time of general bistatic configurations providing a means to derived maps of the range and azimuth spatial resolutions.

Optimal Polarization in Bistatic Scattering
SIAM Journal on Applied Mathematics, 1989The 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.
