Design of ultrasonic synthetic aperture imaging systems based on a non-grid 2D sparse array
(2021-12-01)
This work provides a guide to design ultrasonic synthetic aperture systems for non-grid two-dimensional sparse arrays such as spirals or annular segmented arrays. It presents an algorithm that identifies which elements ...

Design of 2D planar sparse binned arrays based on the Coarray analysis
(2021-12-01)
The analysis of the beampattern is the base of sparse arrays design process. However, in the case of bidimensional arrays, this analysis has a high computational cost, turning the design process into a long and complex ...

Tetrahedral Grid Generators and the Eigenvalue Calculation with Edge Elements
(Revista Computación y Sistemas; Vol. 14 No.1, 2010-09-30)
Abstract. In this work we investigate some computational aspects of the eigenvalue calculation with edge elements; those include: the importance of the grid generator and node-edge numbering. As the examples show, the ...

A sparse spectrum technique for gridding and separating potential field anomalies
(Society of Exploration Geophysicists, 2000-07)
The discrete Fourier transform of a potential field, measured at stations irregularly distributed on a surface, is modeled by means of a high-resolution sparse estimate derived originally for seismic signal processing. The ...
