Analysis of resolution for an amplitude-steered array
Journal of the Acoustical Society of America
In 1976, Hughes and Thompson introduced the idea of steering the maximum response of a linear array by amplitude weighting the output signals of the elements, thus eliminating the need for time delays or phase-shift networks. Currently that amplitude-steered array concept is being extended to a broadband two-dimensional array that can be used for real-time three-dimensional imaging. In shifting the use of the amplitude-steered array from underwater acoustic communications to imaging, we mustdoi:10.1121/1.428629 pmid:10830365 fatcat:3se2xc7qnbcs5f3oulgun3jjuy
