Research on Configuration Constraints of Airborne Bistatic SARs [PDF]
Sensors, 2022 Based on the analysis of the airborne bistatic synthetic aperture radar (SAR) imaging geometric mode, an extended nonlinear chirp scaling algorithm is employed to simulate and verify the imaging effect of the bistatic SARs.

UAV-Based Bistatic SAR-Imaging Using a Stationary Repeater
IEEE Journal of Microwaves, 2023 Synthetic aperture radar (SAR) is an established technique for high-resolution radar imaging relying on the ego-motion of the radar. The long coherent integration time of the radar in conjunction with a linear or circular trajectory enables the ...

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.

An Accelerated Backprojection Algorithm for Monostatic and Bistatic SAR Processing
Remote Sensing, 2018 The backprojection (BP) algorithm has been applied to every SAR mode due to its great focusing quality and adaptability. However, the BP algorithm suffers from immense computational complexity.

SPIE Proceedings, 2014 The problems of simulation of bistatic SAR raw data and focusing are studied. A discrete target simulator is described. The simulator introduces the scene topography and compute the integration time of general bistatic configurations providing a means to derived maps of the range and azimuth spatial resolutions.

Focusing Bistatic FMCW SAR Signal by Range Migration Algorithm Based on Fresnel Approximation
Sensors, 2015 Frequency modulated continuous wave (FMCW) technique has recently been employed by synthetic aperture radar (SAR) to decrease the radar cost and volume. However, the operation range is limited by the direct energy leakage from the transmitting channel to
