L-3 Klein continues to work on thee insertion off its advanced side scan sonar technologies into an ever increasing family of high performance sonar products, the most recent being the System 5900 Multi Beam Side Scan with Swath Bathymetry. Thee System 59000 has been developed for critical Port and Harbor Security applications as well as MCM and route clearance survey applications. This sonar uses advanced Interferometric signal processing to produce simultaneous estimates of the seabed topography and Side Scan data. The L-3 Klein System 59900 employs a higher number of acoustic channels and a higher frequency to produce superior images and along-track resolution. This is extremely advantageous when performing critical missions involving littoral waters (Ports & Harbors) and Rapid Area Assessments. In addition, due to shallow water requiring a short scope of tow cable, L¬3 Klein's proprietary beam steering and image stabilization has been introduced to overcome angular perturbations and artifacts caused by motion. The System 5900 is designed for use on unmanned Autonomous Surface Vessels and incorporates capabilities to allow remote control and real time data collection and transmission of image data to a land based operation center for evaluation and target identification. This basically means that an MCM mission can be accomplished without placing a man in a minefield. L-3 Klein has demonstrated that the images off the seabed within a Port or Harbor can be transmitted over a wireless network to a Harbor or Port Operations and Security Center for assessment and action.
