DOI: 10.1109/jstars.2019.2939194
Abstract: Monitoring large built structures, landslides, volcanoes, or glaciers implies relative height measurements and line-of-sight (LOS) displacement measurements, which are typically performed with monostatic spaceborne synthetic aperture radar (SAR) sensors. In this case, for each satellite…

DOI: 10.1109/lgrs.2018.2810314
Abstract: This letter introduces ground-range and cross-range resolution equations for the side-looking bistatic synthetic aperture radar (SAR). The derivation is based on the backprojection integral and the method of stationary phase. The ground-range and cross-range resolution…

DOI: 10.1109/lgrs.2021.3099174
Abstract: This letter presents coherent and incoherent nonlinear apodization methods for bistatic synthetic aperture radar (SAR) imaging. The methods are developed on the principle of nonlinear apodization for monostatic SAR imaging and a $\omega \,\,-\,\,k$ relationship…

DOI: 10.1109/lgrs.2022.3141845
Abstract: The tilt phenomenon or skew in bistatic synthetic aperture radar (SAR) images has been known. This can be observed from the SAR image of a point-like scatterer, even with a symmetrical bistatic aperture. This letter…

DOI: 10.1109/lgrs.2022.3173680
Abstract: Benefiting from the capability of forward-looking imaging, ability of receiver radio silence, and resistance of jamming, bistatic synthetic aperture radar (SAR) has extensive potential applications. However, due to its independent dual platform movement, motion error…

DOI: 10.1109/tgrs.2022.3214188
Abstract: The goal of this project is to describe the spatially variant imaging performance of bistatic SAR imaging using a localized spatially invariant approximation, so as to use spatial Fourier analysis. Bistatic synthetic aperture radar (BSAR)…
