A compact, integrated acoustic localization and communications array includes an air-backed transmit element having a first end on which an end cap is disposed, and a second end configured to be mounted to a mounting surface. A volumetric acoustic array including a plurality of receiver elements that is electrically integrated to the transmit element. The localization and communications array is configured to transmit, via the transmit element, and receive, via the plurality of the receiver elements, an acoustic signal having a frequency in the range of 10 kHz to 50 kHz. Each of the plurality of receiver elements are spaced apart from the end cap at least a distance. The distance is greater than ¼ of a wavelength associated with the frequency transmitted and received by the localization and communications array, and is not equal to an odd multiple of ¼ of the wavelength.
