www.seadiscovery.com Marine Technology Reporter 63Founded by Marty Klein in a small factory in Salem, NH in 1968, Klein Associates became the first commercial manufacturer of side scan sonar. L-3 Klein Associates has expanded its product offerings to include integrat- ed bridge systems, navigation products and waterside security and surveil- lance systems. Its customers include navies, shipbuilders, secure installa- tions, researchers, oil & gas explorers, and hydrographers. L-3 Klein is still headquartered in Salem, but has a second remote field serv- ice site in Newport News, VA. The Salem location is a design and manufac- turing facility of approximately 56,000 square feet located about 30 miles Northwest of Boston. A Department of Defense Secret facility clearance operating in compliance with the National Industrial Security Operating Manual (NISPOM) is in place at this facility. It contains two sonar test tanks ? the largest of which contains approximately 16,000 cubic feet of water ? a temperature- and humidity-controlled transducer laboratory, and digital design and manufacturing equipment. L-3 Klein engineers specialize in the design and development of acoustic sys- tems capable of operating in extreme marine environments. L-3 Klein engi- neers make use of a variety of engineering tools and systems to design, test, verify, and analyze acoustic systems. These tools include mechanical CAD packages such as Solidworks and AutoCad and finite element analysis (FEA) applications such as COSMOS and Flow Works to design and analyze mechanical structures and assemblies. Electrical design tools such as Orcad and PADS are used for schematic capture and module layout, while embed- ded hardware description language simulation and analysis is done using ModelSim. For data analysis and numerical simulation the engineers use tools such as MatLab, MathCad, and Mathematica. The engineering organ- ization also makes regular use of two on-site acoustic test facilities, which allow for test, measurement, and verification of various acoustic design parameters. There are also two pressure test vessels on the premises that allow for testing mechanical structures and transducers to their full operational depth. Technology Profile: The UUV 3500 was developed as a side scan sonar with an advanced bathymetry payload for the growing Autonomous Underwater Vehicle (AUV), Remotely Operated Underwater Vehicle (ROV) and UUV markets. L-3s UUV 3500 product line leverages multi-channel processing electronics, offering both photo-quality side scan imagery and swath bathymetry. In addition, the new sys- tem utilizes L-3 Kleins proprietary wideband technology while operating at lower power. In 2010, L-3 Kliens product lineup also included the Klein 3000, the Klein 3900 SAR, the Multi-beam Klein 5000 V2 (available with interferometric bathymetry), and the Klein 5900 minehunting SSS. This year, the company intro- duced the HydroChart 5000 hydrography system, which com- bines high-resolution 455 kHz Multibeam side scan sonar with high-definition Interferometric bathymetry sonar. The HydroChart 5000 utilizes a phase difference measurement tech- nique and Linear FM (Chirp) processing to produce data sets for the hydrographic industry. The system was designed to reduce survey times, and may be hull mounted or pole mounted.
