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,

Unambiguous signal reconstruction for GEO-LEO bistatic SAR with azimuth multichannel
The Journal of Engineering, 2019 Spaceborne bistatic multichannel synthetic aperture radar (MC-SAR) system employed inclined geosynchronous Earth orbit (GEO) transmitter and low-Earth-orbit (LEO) receiver can provide fine spatial resolution and a vast area of surveillance, which ...

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.

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.

Performance Comparison between Monostatic and Bistatic Staring Spotlight Modes Based on Several Scenarios [PDF]
Journal of Electromagnetic Engineering and ScienceThis paper analyzes the performance of the bistatic staring spotlight mode in a low-orbit satellite environment and then compares it with the performance of the monostatic staring spotlight mode. The staring spotlight mode provides high-resolution images

Bistatic SAR experiments with the TanDEM-X constellation [PDF]
2012 IEEE International Geoscience and Remote Sensing Symposium, 2012 Launched in June 2010, TanDEM-X is an interferometric mission with the main goal of providing a high-resolution, global and unprecedentedly accurate digital elevation model (DEM) of the Earth by means of single-pass X-band SAR interferometry. Despite its usual quasi-monostatic configuration, TanDEM-X is the first genuinely bistatic SAR system in space.
