Synthetic Aperture Imaging With Intensity-Only Data. [PDF]
, 2020 We consider imaging the reflectivity of scatterers from intensity-only data recorded by a single moving transducer that both emits and receives signals, forming a synthetic aperture.

Bayesian off-line detection of multiple change-points corrupted by multiplicative noise : application to SAR image edge detection [PDF]
, 2003 This paper addresses the problem of Bayesian off-line change-point detection in synthetic aperture radar images. The minimum mean square error and maximum a posteriori estimators of the changepoint positions are studied.

Ultrasonic Synthetic Apertures: Review
Archives of Acoustics, 2014 In the paper the concept of synthetic aperture used for high resolution/high frame rate ultrasonic imaging is reviewed. The synthetic aperture technique allows building extended “virtual” apertures, synthesized from smaller real aperture resulting in ...

Synthetic aperture-based linear-array photoacoustic tomography considering the aperture orientation effect [PDF]
Journal of Innovative Optical Health Sciences, 2018 The synthetic aperture-based linear-array photoacoustic tomography (PAT) was proposed to address the limited-view shortcomings of the single aperture, but the detection field of view (FOV) determined by the aperture orientation effect was not fully ...

Focus Measure for Synthetic Aperture Imaging Using a Deep Convolutional Network
IEEE Access, 2019 Synthetic aperture imaging is a technique that mimics a camera with a large virtual convex lens with a camera array. Objects on the focal plane will be sharp and off the focal plane blurry in the synthesized image, which is the most important effect that
