Claim 12:
13. The system of claim 1,
wherein the at least one acoustic sensor comprises a plurality of acoustic sensors arranged in a tetrahedral configuration, and
wherein the plurality of machine-readable instructions, when executed by the at least one computer processor, cause the at least one computer processor to perform the following steps when one of an azimuth angle and an elevation angle in relation to an object origin is known:
determine the one of the azimuth angle and the elevation angle that is unknown based on at least one of a time of arrival of a muzzle blast and a time of arrival of a shockwave associated with the object with relation to each acoustic sensor of the at least one acoustic sensor; and
use the azimuth angle and the elevation angle to determine a distance to the object origin.
