Range Linearization for Bistatic SAR

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
In 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.

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

Research on Bistatic SAR Imaging

2006 IEEE International Symposium on Geoscience and Remote Sensing, 2006
For 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.

Oceanographic applications of spaceborne bistatic SAR

IGARSS 2003. 2003 IEEE International Geoscience and Remote Sensing Symposium. Proceedings (IEEE Cat. No.03CH37477), 2004
This work presents an analysis of the attainable performance of a bistatic SAR for oceanographic applications, such as the determination of sea state parameters and the reconstruction of the sea wave spectrum. The analysis has been developed with regard to the spaceborne bistatic SAR of the BISSAT mission.

Bistatic SAR: Forecasting Spatial Resolution

IEEE Transactions on Aerospace and Electronic Systems, 2019
This paper derives closed-form expressions for bistatic synthetic aperture radar (SAR) spatial resolution of a generalized system from the $k$ -space or the wavenumber domain. These spatial resolution equations have not previously appeared in the literature.

Low frequency bistatic SAR measurements

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
Airborne bistatic SAR data have been collected at VHF- and UHF-band to investigate clutter suppression in forested and urban areas. The synchronization between the SAR systems is accomplished using the 1-PPS signal provided by the GPS system. The same signal is also used as input to a disciplined 10 MHz master oscillator integrated in both radar ...

Experimental results with bistatic SAR tomography

2009 IEEE International Geoscience and Remote Sensing Symposium, 2009
This paper gives a quick overview of inversion methods for bistatic tomographic processing. The methods are tested over simulated and real data. The real data has been acquired from a set of indoor experiments carried out in the Radiation Laboratory (RadLab), at the University of Michigan.

Bistatic parasitic SAR processor evaluation

IEEE International IEEE International IEEE International Geoscience and Remote Sensing Symposium, 2004. IGARSS '04. Proceedings. 2004, 2004
Bistatic radar systems will pay a great role in the coming decade since a large number of radar missions are being foreseen. Using existing transmitters, formations of small passive receivers will enhance our capability to gather backscatter information from Earth.

Performance Simulator for Bistatic SAR Missions

IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018
This paper presents a Synthetic Aperture Radar (SAR) simulator designed to assess the performance of bi-static SAR missions. It is a modular software able to simulate realistic SAR data (including injection of the system non-idealities), to estimate the SAR performance at radiometric and interferometric level.

Fundamentals of Bistatic SAR

2017
Bistatic SAR (BiSAR) has been developing for 40 years, and it is still a topic of much discussion in the field of radar. BiSAR is a SAR system whose transmitter and receiver are spatially separated. This separation improves the system’s capability, reliability and flexibility, making it a promising and useful supplement to a classical monostatic SAR ...
