A tutorial on synthetic aperture radar [PDF]

open access: yesIEEE Geoscience and Remote Sensing Magazine, 2013
Synthetic Aperture Radar (SAR) has been widely used for Earth remote sensing for more than 30 years. It provides high-resolution, day-and-night and weather-independent images for a multitude of applications ranging from geoscience and climate change research, environmental and Earth system monitoring, 2-D and 3-D mapping, change detection, 4-D mapping (

Ultrasound synthetic aperture non-line-of-sight imaging [PDF]

open access: yesCommunications Physics
Non-line-of-sight (NLOS) imaging typically relies on the use of ultrashort laser pulses and time-resolved detection to then reconstruct 3D environments that are hidden from the direct line-of-sight.

Compressed Synthetic Aperture Radar [PDF]

open access: yesIEEE Journal on Selected Topics in Signal Processing, 2010
In this paper, we introduce a new synthetic aperture radar (SAR) imaging modality which can provide a high-resolution map of the spatial distribution of targets and terrain using a significantly reduced number of needed transmitted and/or received electromagnetic waveforms.

Synthetic Aperture Scatter Imaging

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Diffraction limits the minimum resolvable feature on remotely observed targets to $\lambda R_{c}/A_{c}$, where $\lambda$ is the operating wavelength, $R_{c}$ is the range to the target and $A_{c}$ is the diameter of the observing aperture.

Uncertainty Estimation for Deep Learning-Based Segmentation of Roads in Synthetic Aperture Radar Imagery

open access: yesRemote Sensing, 2021
Mission-critical applications that rely on deep learning (DL) for automation suffer because DL models struggle to provide reliable indicators of failure.

Synthetic Aperture Anomaly Imaging

open access: yesCoRR, 2023
Previous research has shown that in the presence of foliage occlusion, anomaly detection performs significantly better in integral images resulting from synthetic aperture imaging compared to applying it to conventional aerial images. In this article, we hypothesize and demonstrate that integrating detected anomalies is even more effective than ...

Interferometric synthetic aperture microscopy [PDF]

open access: yesNature Physics, 2007
State-of-the-art methods in high-resolution three-dimensional optical microscopy require that the focus be scanned through the entire region of interest. However, an analysis of the physics of the light-sample interaction reveals that the Fourier-space coverage is independent of depth.

Synthetic Aperture Hitchhiker Imaging [PDF]

open access: yesIEEE Transactions on Image Processing, 2008
We introduce a novel synthetic-aperture imaging method for radar systems that rely on sources of opportunity. We consider receivers that fly along arbitrary, but known, flight trajectories and develop a spatio-temporal correlation-based filtered-backprojection-type image reconstruction method. The method involves first correlating the measurements from
