Bistatic Synthetic Aperture Radar Imaging for Arbitrary Flight Trajectories [PDF]
IEEE Transactions on Image Processing, 2008 In this paper, we present an analytic, filtered backprojection (FBP) type inversion method for bistatic synthetic aperture radar (BISAR). We consider a BISAR system where a scene of interest is illuminated by electromagnetic waves that are transmitted, at known times, from positions along an arbitrary, but known, flight trajectory and the scattered ...

Bistatic ISAR sparse aperture maneuvering target translational compensation imaging algorithm [PDF]
Radioengineering, 2022 For bistatic inverse synthetic aperture radar (Bi-ISAR), the non-uniform motion state of maneuvering target and the time-varying bistatic angle make the traditional imaging method of moving target face the problem of translation compensation, and the ...

IEEE Access, 2023 We have proposed a novel process flow for translational-invariant (TI) and ultrahigh-resolution (UHR) bistatic synthetic aperture radar (BSAR) operations, wherein a UHR BSAR image is obtained via coherent integration of sub-aperture images, and its two ...

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

A Fast Bistatic ISAR Imaging Approach for Rapidly Spinning Targets via Exploiting SAR Technique
Remote Sensing, 2020 Because of the large range of cell migration (RCM) and nonstationary Doppler frequency modulation (DFM) produced by non-cooperative targets with rapid spinning motions, it is difficult to efficiently generate a well-focused bistatic inverse synthetic ...

Resolution and Micro-Doppler Effect in Bi-ISAR System (in English)
Leida xuebao, 2013 Compared to the monostatic radar, bistatic radar has many special characteristics because of its spatial complexity. Bistatic Inverse Synthetic Aperture Radar (Bi-ISAR) can be employed as a radar imaging tool for obtaining non-cooperative target images ...

Results on bistatic synthetic aperture radar
Electronics Letters, 2004 The interest in bistatic synthetic aperture radar (SAR) has increased rapidly in recent years. This is founded in the specific advantages of bistatic SAR configurations. The calculation of the resulting bistatic resolution is quite different from the monostatic case. A general vectorial calculation in three-dimensional space is presented.
