Abstract

A new method of data acquisition from large aperture sensor arrays is suggested by deliberate randomization of temporal and spatial sampling of array signals and using iterative processes. Also, a distributed analog-to-digital converter structure is suggested, comprising sample and hold devices for simultaneous sampling of sensors.
