Abstract
A ultrasonic sensor for detecting the location of objects disposed in a substantially gaseous environment includes a plurality of nodes arranged into a uniform network. A plurality of circular transducers are provided such that each transducer is disposed at a node. The center of adjacent transducers are spaced at a distance no greater than the wavelength of acoustic waves emitted by the transducers. A method of detecting the location of objects disposed in a substantially gaseous environment is also disclosed.
