This means an area can be cov- ered at twice the speed while still maintaining 100% bot- tom coverage, or one can get double the bathymetric data density along track. The 4600 provides a swath of up to 12 times water depth for bathymetric data, and a range of up to 250 meters/side for the side scan sonar, which oper- ates at a 230 kHz frequency providing a great combination of range and high resolution CHIRP data. The LMCS is a highly advanced mine and underwater IED hunting system designed for small boat and unmanned surface vehicle operations. The LMCS com- bines EdgeTech’s proprietary Dynamically Focused and Multi-Pulse side scan sonar tech- nologies provid- ing exceptional swath coverage and ultra high resolutions. The system’s active towfish, designed by Vehicle Control Technologies (VCT), delivers unparalleled steadiness and ease of opera- tions, even from small craft. The result is an affordable, state- of-the-art, commercial off the shelf (COTS) mine warfare sonar system. The LMCS System is outfitted with a 600/1600 kHz dual frequency sonar. The 600 kHz fre- quency utilizes both the Multi-Pulse technology and Dynamically Focused transducers for high resolution mine detection at ranges up to 125 meters per side at speeds of up to 14 knots. The 1600 kHz frequency utilizes Dynamically Focused transducers for detailed classifica- tion and identification of mine and IED-like targets with resolutions down to .8 cm. This rapidly-deployable system provides real-time sonar images allowing operators the ability locate, classify, mark and record mine-like objects and underwater terrain features.
