Interferometric Passive Radar Imaging with Deep Denoising Priors [PDF]
arXiv, 2022 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 using a spectral estimation method with a priori information within a deep learning (DL) framework.

Applications of microlocal analysis to some hyperbolic inverse problems [PDF]
, 2015 This thesis compiles my work on three inverse problems: ultrasound recovery in thermoacoustic tomography, cancellation of singularities in synthetic aperture radar, and the injectivity and stability of some generalized Radon transforms.

Photonics-Based High-Resolution 3D Inverse Synthetic Aperture Radar Imaging
IEEE Access, 2019 A photonics-based radar for high-resolution 3D microwave imaging is proposed and demonstrated, in which high range resolution is achieved by employing a wideband linearly frequency modulated signal, and high cross-range resolution in both azimuth and ...

AutoSAFT: Autofocusing for extended depth of imaging in scanning acoustic microscopy
Journal of Microscopy, EarlyView.Abstract In the scanning acoustic microscopy (SAM) imaging, it is essential to address the diminished lateral resolution in the out‐of‐focus region, as image quality correlates with the ultrasound propagation distance either above or below the focal plane.

Multiple feature-enhanced synthetic aperture radar imaging [PDF]
, 2009 Non-quadratic regularization based image formation is a recently proposed framework for feature-enhanced radar imaging. Specific image formation techniques in this framework have so far focused on enhancing one type of feature, such as strong point ...

Computer-Aided Civil and Infrastructure Engineering, EarlyView.Abstract In structural health monitoring, only the deflection of key sections of the bridge can be monitored; the spatial continuous deflection of the main girder cannot be identified. To solve this problem, a method for expanding sparse point deflection measurements to spatially continuous data via optical fiber sensors in long‐span suspension bridges

Differentiable Rendering for Synthetic Aperture Radar Imagery [PDF]
arXiv, 2022 There is rising interest in differentiable rendering, which allows explicitly modeling geometric priors and constraints in optimization pipelines using first-order methods such as backpropagation. Incorporating such domain knowledge can lead to deep neural networks that are trained more robustly and with limited data, as well as the capability to solve

Multi-static synthetic aperture radar and inverse scattering [PDF]
, 2004 In this paper synthetic aperture radar is analyzed from an inverse scattering perspective. It is shown that the classical point scattering model can be generalized to a dipole scattering model.
