Improving synthetic aperture image by image compounding in beamforming process
(2011-11-10)
In this work, signal processing techniques are used to improve the quality of image based on multi-element synthetic aperture techniques. Using several apodization functions to obtain different side lobes distribution, a ...
Synthetic aperture ultrasound imaging using GPUs
(Institute of Electrical and Electronics Engineers Inc., 2017-01)
Ultrasound images are widely used for medical diagnosis and for Non-Destructive Testing (NDT) in the industry. Among alternative imaging methods there are the Phased Array techniques, which allow processing ultrasound ...
Sparse arrays and image compounding techniques for non-destructive testing using guided acoustic waves
(2013-06-01)
Piezoelectric array transducers applications are becoming usual in the ultrasonic non-destructive testing area. However, the number of elements can increase the system complexity, due to the necessity of multichannel ...

Synthetic aperture sonar images segmentation using dynamical modeling analysis
(Sociedade Brasileira de GeofísicaRio de Janeiro, 2013)
Symbolic Models applied to Synthetic Aperture Sonar images are proposed in order to assess the validity and reliability of use of such models and evaluate how effective they can be in terms of image classification and ...
Empirical Removal of Tides and Inverse Barometer Effect on DInSAR From Double DInSAR and a Regional Climate Model
(Institute of Electrical and Electronics Engineers, 2020-07-10)
Ice shelves-the floating extensions of the Antarctic ice sheet-regulate the Antarctic contribution to sea-level rise by restraining the grounded ice flowing from upstream. Therefore, ice-shelf change (e.g., ice-shelf ...
Synthetic Aperture Radar Automatic Target Recognition Based on a Simple Attention Mechanism
A simple but effective channel attention module is proposed for Synthetic Aperture Radar (SAR) Automatic Target Recognition (ATR). The channel attention technique has shown recent success in improving Deep Convolutional ...
