Bistatic foliage penetration modelling
2007 IEEE International Geoscience and Remote Sensing Symposium, 2007This paper aims at presenting a model able to study the impact of the target presence under vegetation and to assess the detection feasibility. In a first part the model is described. We will then get at the analysis of results for several set of radar configurations to illustrate the potentiality of detection by means of shadows.

Range Linearization for Bistatic SAR
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018In bistatic SAR, range is difficult to be linearized for the complicated geometry. In this paper, comparing to monostatic SAR, a modified range direction is derived based on vector analysis. The scatters along this direction will be imaged to the same azimuth cell which is important for the nonlinear chirp scaling (NLCS) algorithm.

A bistatic polarimeter calibration technique
IEEE Transactions on Geoscience and Remote Sensing, 1995A procedure for calibrating a bistatic polarimeter system without using reference scattering targets is described. Transmitter and receiver subsystem distortion matrices are determined via transmission link measurements in conjunction with an inexpensive test source and a linearly polarized test antenna. >

Resolution analysis of bistatic SAR
SPIE Proceedings, 2011In 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

Research on Bistatic SAR Imaging
2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006For reasons of stealth and other operational advantages, more attention has recently been focused on bistatic SAR Bistatic SAR uses separated transmitter and receiver flying on different platforms, and has the ability of the exploitation of additional information contained in the bistatic reflectivity of targets.

Bistatic Multipositional Wave Tomography
Russian Physics Journal, 2015A method of bistatic multipositional wave tomography is proposed that is applicable both for the case of radiowave sensing and for the case of ultrasonic sounding. A sensing system is considered in which the transmitter and the receiver are displaced independently in a plane above the investigated object.

Bistatic model of ocean scattering
IEEE Transactions on Antennas and Propagation, 1998An 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 ...

A Solution for Bistatic Motion Compensation
2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006Bistatic synthetic aperture radar (SAR) missions have become attractive in the last years, because of their higher degree of freedom in choosing transmitter and (passive) receiver motion trajectories. In order to take advantage of this increased imaging flexibility, adequate processing algorithms have to be developed, implemented and verified with ...

BISSAT: a bistatic SAR for Earth observation
IEEE International Geoscience and Remote Sensing Symposium, 2003This paper summarizes scientific rationale and technical approach for a bistatic synthetic aperture radar (SAR) mission (BISSAT). The study has been funded by the Italian Space Agency for a competitive Phase-A study along with other five missions.
