Exploration of Advanced Bistatic SAR Experiments (in English)
Leida xuebao, 2014 This study concentrates on the results of several advanced hybrid bistatic SAR experiments. The hybrid bistatic configuration applies to the case in which the transmitter and receiver are mounted on different types of platforms, e.g., spaceborne/airborne,

On bistatic forward-looking SAR imaging
2014 IEEE Geoscience and Remote Sensing Symposium, 2014 Left/right ambiguity and low angular (azimuth) resolution are severe problems for monostatic forward-looking SAR imaging. It is strongly believed that these technical issues can definitely be solved with bistatic forward-looking SAR. The analysis presented in this paper points out that the left/right ambiguity problem still exits.

Spaceborne Bistatic SAR Scene Simulation [PDF]
IGARSS 2018 - 2018 IEEE International Geoscience and Remote Sensing Symposium, 2018 Augmenting traditional spaceborne SAR sensors with additional receive-only satellites in close formation enhances the observation space, allowing for single-pass interferomtry in along-and/or across-track with flexible baselines and the potential to build tomographic stacks with reduced temporal decorrelation properties. The feasibility of such add-ons

IET Radar, Sonar & Navigation, 2007 With the present revival of interest in bistatic radar systems, research in that area has gained momentum. Given some of the strategic advantages for a bistatic configuration, and tech- nological advances in the past few years, large-scale implementation of the bistatic systems is a scope for the near future.

Bistatic 3D SAR for wall parameter extraction in cluttered environments
Electronics Letters, 2021 Through‐wall radar is an emergent technology rooted in urban surveillance, a key component being synthetic aperture radar (SAR). Accurate through‐wall SAR relies on knowledge of the refractive index and thickness of any obscuring walls.
