The Lightweight Towed Array Receiver (LTAR) project was initiated in 2009 when a team of Northeastern University scientists partnered with Einhorn Engineering to develop a receiver array suite as part of a lightweight, acoustic system for rapid, wide-area monitoring and measurement of the ocean environment.
This Ocean Acoustic Waveguide Remote Sensing (OAWRS) suite includes both the LTAR (passive receiver) and FMP (active source) equipment. The LTAR system is tailored as a general-purpose, mobile, remote sensing tool to study marine life, oceanography, and geologic and geophysical properties of the ocean environment. It is designed to be used in stand-alone, passive sensing applications as well as active sensing deployments when paired with the OAWRS Source Array.
Einhorn Engineering was selected to provide the mechanical engineering services required to design and oversee the fabrication of the handling system. This included the specification of a custom tow cable, development and fabrication of the wet side junction box sub-assembly, and a handling system designed to be quickly mobilized on a vessel of opportunity.
