Filippo Biondi is an Italian aerospace engineer and researcher specializing in remote sensing , signal processing, and synthetic aperture radar (SAR) technology. He is particularly known for his development and application of SAR-Doppler Tomography techniques for high-resolution imaging.

He is affiliated with HarmonicSAR.com, where he conducts harmonic analysis of SAR data, and has previously held research positions including at the University of Strathclyde . His work includes advanced radar applications, with peer-reviewed publications on SAR tomography, including a study of the internal structure of the Great Pyramid of Giza.

Biondi has gained public attention through his involvement in radar-based archaeological research and media appearances.

Limited publicly available details exist on Filippo Biondi's early life, education, and formative experiences prior to advanced studies.

Filippo Biondi is an Italian aerospace engineer specializing in remote sensing, signal processing, and synthetic aperture radar (SAR) technologies. He has been affiliated with the University of L'Aquila , where he conducted much of his early research and doctoral work in related fields.

Between 2022 and 2024, Biondi held an affiliation with the University of Strathclyde in Glasgow, Scotland, contributing to advanced SAR and signal processing research within its academic environment.

More recently, Biondi has pursued independent research and development through HarmonicSAR.com, a platform dedicated to innovative SAR applications and consulting services. This shift reflects a transition from conventional academic positions to self-directed professional activities focused on specialized remote sensing technologies.

Filippo Biondi has made foundational contributions to synthetic aperture radar (SAR) and signal processing, with a focus on techniques to enhance image resolution, recover corrupted data, and detect features in complex radar scenes. His early work from 2016 onward emphasized super-resolution and decomposition methods applied to SAR imagery , often leveraging compressed sensing and statistical signal processing principles.

In 2016, Biondi developed a super-resolution approach for recovering partially corrupted SAR images based on spectrum extrapolation, enabling restoration of spatial details beyond standard resolution limits by extending the signal spectrum. He also explored convex optimization for super-resolution of SAR data, formulating the problem to achieve higher resolution through constrained reconstruction.

A key area of his research involves low-rank plus sparse decomposition of SAR data, which separates background clutter (low-rank component) from sparse anomalies or targets. In 2016, he applied this decomposition to SAR imagery for maritime surveillance applications. He advanced the method in 2017 by integrating a localized Radon transform, improving detection of ship wakes in SAR images for maritime monitoring. In 2018, Biondi extended the framework to polarimetric SAR, incorporating polarization diversity to enhance ship wake detection accuracy.

Biondi's signal processing expertise further supported maritime surveillance through micro-motion analysis of targets. In 2019, he used pixel tracking and convex optimization on COSMO-SkyMed staring spotlight SAR data to estimate ship micro-motions and inclination angles.

His techniques have also addressed environmental monitoring applications. These include classification of covariance matrix eigenvalues in polarimetric SAR for environmental purposes (2019) and multi-chromatic polarimetric interferometric SAR analysis for urban classification (2019). Biondi's contributions in these areas demonstrate his application of advanced signal processing to improve SAR data utility across maritime and environmental domains.
