Four-Dimensional Remote Sensing of the Marine Boundary Layer with a Digital Beamforming Radar Wind Profiler.

摘要

This report details research performed by Quadrant Engineering under ONR SBIR contract no. N00014-93-C-0042. The purpose of this study was to determine the feasibility of deploying a shipboard turbulent eddy profiling (TEP) radar system for studying the dynamics of the marine boundary layer. A similar system is currently being developed by the University of Massachusetts to study the atmospheric boundary over land. During the phase I study, Quadrant Engineering reviewed the design of the land based system, and determined that a slightly scaled down version of that system would be suitable for deployment on a large research vessel, such as the Knorr, operated by Woods Hole Oceanographic Institute. In this report, we present a design for the shipboard TEP system and consider the particular requirements of installation on the Knorr. We also describe the application of TEP to boundary layer research, especially in terms of complimenting Large Eddy Simulation (LES) models.
