In this paper, bistatic interferometry using fixedreceiver configurations is addressed both theoretically and experimentally. The analytical expressions for interferometric phase and height sensitivity are derived, and a full interferometric processing chain for digital elevation model (DEM) generation is presented. The derived expressions are general, and they can be applied to two possible acquisition geometries: backscattering and forward scattering. The theoretical developments are complemented with experimental results done with the bistatic receiver Synthetic Aperture radar Bistatic Receiver for INterferometric Applications. The obtained DEMs are compared with a DEM from the Shuttle Radar Topography Mission and a digital terrain model from the Institut Cartografic de Catalunya. The comparison allows one to validate the results and demonstrate to which particular features of the scene that the bistatic radar is sensitive.

“…The back-projection (BP) algorithm [6] can serve most cases, but its low efficiency makes it not a good choice. Reference [7]- [8] studies the one-stationary case, and points out that those targets at the same range gate but different azimuth position have different RCMs and Doppler FM rates. Reference [8] applies the non-linear chirp scaling rule to azimuth signal to identify the Doppler FM rate in one range gate.…”

This paper points out the non-linear property of the differential RCM along range direction in onestationary bistatic SAR, and compares it with the monostatic case. Then it deduces out a non-linear chirp scaling factor to identify the RCM of all targets in the swath. The implementary processes of a non-linear chirp scaling algorithm for one-stationary bistatic SAR are then described detailedly. Finally, the simulating results present here validate the correctness of the algorithm.

“…In recent years, many bistatic SAR models and processing methods are presented [1][2][3][4][5] , and some encouraging experiments [6][7][8][9] are conducted, which demonstrate the feasibility of bistatic SAR system. The University of Electric Science and Technology of China (UESTC) is the first organization that carried out the research of bistatic SAR system in China.…”

in this paper, we discuss the translational-variant feature of translational-variant bistatic SAR configuration using the space Taylor's expansion in section II. In section III, a new translational-variant bistatic SAR imaging method is proposed, which uses scaled IFFT technique to eliminate the translationalvariant feature of SAR space resolution. Finally, some numerical experiments are conducted to demonstrate the feasibility of this method and discuss the depth-of-focus of the scaled IFFT bistatic SAR imaging algorithms.
