Interferometric Passive Radar Imaging with Deep Denoising Priors
Samia Kazemi, Bariscan Yonel, Birsen Yazici
Passive radar has key advantages over its active counterpart in terms of cost and stealth. In this paper, we address passive radar imaging problem by interferometric inversion usin…
A Spectral Estimation Framework for Phase Retrieval via Bregman Divergence Minimization
Bariscan Yonel, Birsen Yazici
In this paper, we develop a novel framework to optimally design spectral estimators for phase retrieval given measurements realized from an arbitrary model. We begin by deconstruct…
Exact Imaging of Extended Targets Using Multistatic Interferometric Measurements
Bariscan Yonel, Il-Young Son, Birsen Yazici
In this paper, we present a novel approach that can exactly recover extended targets in wave-based multistatic interferometric imaging, based on Generalized Wirtinger Flow (GWF) th…
A Generalization of Wirtinger Flow for Exact Interferometric Inversion
Bariscan Yonel, Birsen Yazici
Interferometric inversion involves recovery of a signal from cross-correlations of its linear transformations. A close relative of interferometric inversion is the generalized phas…
Deep Learning for Waveform Estimation and Imaging in Passive Radar
Bariscan Yonel, Eric Mason, Birsen Yazici
We consider a bistatic configuration with a stationary transmitter transmitting unknown waveforms of opportunity and a moving receiver, and present a Deep Learning (DL) framework f…
