ABF Algorithms Implemented at ARL:UT, Technical Report Under Contract N00039-91-C-0082, TD No. 01A1002, FDS System Engineering and Acoustics

Abstract

Two adaptive beamforming (ABF) algorithms have been implemented at ARL:UT in order to assess algorithm performance. Using data obtained with ARL:UT acoustic data acquisition systems, these algorithms are being used to assess performance of future surveillance systems. This report describes the two element-level ABF algorithms implemented thus far at ARL:UT. They are the single point constraint ABF and multiple linear constraint ABF. Both algorithms have a quadratic white noise gain constraint included in the implementation. This report also provides some details on how the algorithms have been programmed on the ARL:UT Alliant mini-supercomputer. Examples of the ABF output are also included and briefly discussed.
