Founded by Marty Klein in 1968, in a small factory in Salem, New Hampshire, USA, Klein Associates became the first commercial manufacturer of side scan sonar in the world. Since then, L-3 Klein Associates has become the leading supplier of side scan sonar equipment, and waterside security and surveillance systems to navies, shipbuilders, secure installations, researchers, oil & gas explorers, and hydrographers all over the globe.
In 2010, we’re proud to announce that in addition to our highly successful product lineup that includes the workhorse Klein 3000, the immensely-popular Klein 3900 SAR, the industry-standard true Multi-beam Klein 5000 V2 (available with interferometric bathymetry), and the most powerful minehunting SSS of all-time, the Klein 5900.
In 2011, we introduced the all-new HydroChart 5000 hydrography system that combines high-resolution 455 kHz Multibeam side scan sonar with high-definition Interferometric bathymetry sonar for the most spectacular IHO quality imagery possible. In addition, we also introduced the UUV-3500 High Resolution Side Scan sonar for UUVs. The UUV-3500 operates exclusively with L-3 Klein’s proprietary wideband technology providing unmatched side scan range and resolution performance in a low power, compact and lightweight payload.
In 2012 we have introduced our all-new HydroScan®, professional-grade side scan sonar for shallow water and rapid-deployment applications.
The System 5900 Multi-Beam Side Scan Sonar represents Klein’s advanced multi-function sonar platform and includes the following key features: high resolution multi-beam side scan sonar, swath bathymetry sonar, gap filler sonar, and integrated tow body sensor and subsystems. The sonar employs advanced signal processing techniques and superior acoustic design to improve overall along track target resolution. The S5900 high speed, high resolution, side scan sonar performance capabilities, when coupled with the gap filler sonar for fast coverage rates makes the system an ideal choice for MLO detection, classification, Q-Route surveys and rapid area reconnaissance.
The UUV 3500 was developed as a side scan sonar with the unprecedented benefit of an advanced bathymetry payload for the growing Autonomous Underwater Vehicle (AUV), Remotely Operated Underwater Vehicle (ROV) and UUV markets.
The HydroChart 5000 represents the latest technology for the acquisition; display and processing of highly accurate bathymetry data integrated with high resolution side scan imagery, meeting IHO SP-44 Special Order Standards. The HydroChart 5000 utilizes a phase difference measurement technique and Linear FM (Chirp) processing, to produce the highest quality data sets for the hydrographic industry. The HydroChart 5000 reduces survey times in half compared to conventional surveys using Multi-beam echo sounder systems.
With over 35 years of experience, L-3 Klein is the worldwide leader in commercial Side Scan Sonar systems.
