Sigma Tech Corporation has been providing system engineering, hardware design and custom software solutions to commercial and government customers since 1993.  We specialize in digital processing applications ranging from small embedded solutions to large multi teraflop systems.

Sigma Tech has designed numerous acoustic Anti Submarine Warfare (ASW) solutions for both shipboard and airborne use. The MARS, MARS II, and ABS signal processors were developed for SURTASS/LFA as bistatic active processors for US Navy frigates and destroyers.  The AirMARS, TSAP and TSAP2 systems were developed for airborne ASW platforms using active sonobuoys.

On the commercial front we developed a unique system in partnership with Pipeline Technology to acoustically determine the likely failure rate of prestressed concrete pipelines.
