DOCUMENTED BRIEFING R Rapid Force Projection Technologies Assessing the Performance of Advanced Ground Sensors John Matsumura, Randall Steeb, Randall G. Bowdish, Scot Eisenhard, Gail Halverson, Thomas Herbert, Mark Lees, John D. Pinder Prepared for the United States Army Office of the Secretary of Defense Arroyo Center National Defense Research Institute Approved for public release; distribution unlimited PREFACE This documented briefing summarizes the research emerging from an ongoing RAND project that has been supporting the Rapid Force Protection Initiative (RFPI) Advanced Concept Technology Demonstration (ACTD). This project was jointly sponsored by the Office of the Assistant Secretary of the Army for Research, Development, and Acquisition and the Office of the Under Secretary of Defense (Acquisition and Technology) with the goal of exploring new technology concepts for the ACTD. The focus of this year’s research was on advanced ground sensors—specifically the air-deliverable acoustic sensor (ADAS)—with emphasis on how such sensors might fit into the current RFPI hunter–standoff killer concept. High-resolution simulation was used to examine and quantify many of the key aspects of performance, environmental effects, and military utility. This work has been shared with those involved in the ACTD, including the RFPI ACTD program offices. This work should be of interest to defense policymakers, acquisition executives, concept developers, and technologists. The research was conducted in the Force Development and Technology Program of RAND’s Arroyo Center and the Acquisition Technology Policy Center of RAND’s National Defense Research Institute (NDRI). Both the Arroyo Center and NDRI are federally funded research and development centers, the first sponsored by the United States Army and the second sponsored by the Office of the Secretary of Defense, the Joint Staff, the unified commands, and the defense agencies. -

PNNL-23110 Pacific Northwest National Laboratory, Seattle, Washington. Summary As the marine energy industry explores the potential for generating significant power from waves and tidal currents, there is a need to ensure that energy converters do not cause harm to the marine environment, including marine animals that may interact with these new technologies in their native habitats. The challenge of deploying, operating, and maintaining marine energy converters in the ocean is coupled with the difficulty of monitoring for potentially deleterious outcomes between the converters, anchors, mooring lines, power cables and other gear, and marine mammals, sea turtles, fish, and seabirds. To better understand the state of instrumentation and capabilities for monitoring around marine energy converters, the U.S. -

Josso et al. This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. The underwater environment can be considered a system with time-varying impulse response, causing time-dependent spectral changes to a transmitted acoustic signal. This is the result of the interaction of the signal with the water column and ocean boundaries or the presence of fast moving object scatterers in the ocean. In underwater acoustic communications using medium- to-high frequencies (0.3–20 kHz), the nonstationary transformation on the transmitted signals can be modeled as multiple time- delay and Doppler-scaling paths. When estimating the channel, a higher processing performance is thus expected if the techniques used employ a matched channel model compared to those that only compensate for wideband effects. Following a matched linear time-varying wideband system representation, we propose two different methods for estimating the underwater acoustic communication environment.
