Bistatic SAR image registration accuracy [PDF]
2015 IEEE Radar Conference (RadarCon), 2015 An investigation of the effect of bistatic angle on the accuracy of registering a monostatic image of a target to a bistatic image of the same target is presented in this paper. Cross-correlation registration degradation is related to the decorrelation of a monostatic image with a bistatic image with respect to bistatic angle.

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.

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
