Summary of Field Work: |
This study seeks to characterize significant wave height using passive, bistatic radar measurements of reflections from XM Radio signals. To this end, the study will investigate an extension of bistatic ocean remote sensing techniques to Doppler processing of off-specular scattering from ocean waves.
A large-scale cruise would ideally be scheduled to include a variety of significant wave height (SWH) conditions. We would like to navigate to within a few kilometers of several wave rider buoys off the East coast, as the data from the buoys is used as ground truth for our experiments. We would expect to be at sea for a period of about two weeks -- if the ship needs to come to port during that time, that is okay. |
|
Summary of Facility Requirements: |
We will need a spot on the weather deck on which to mount the passive radar antennas, which can be deployed on a single tripod whose footprint is less than 3 square meters. We would like an unimpeded view of the ocean in as many cardinal directions as possible. We will also need an air-conditioned workspace indoors to keep the back-end electronics cool, with vias to the outdoor tripod over which to run the radio-frequency coaxial cables. Our equipment runs on 120VAC and draws less than 2 amps -- we have a means of "cleaning" the power ourselves, i.e. this can be provided directly from a generator. Satellite internet access would be helpful, but not necessary. |

Justification/Explanation for ship choice, dates,
conflicts, number of days & multi-ship operations: |
The home port of the Hugh R. Sharp is close to NRL-DC, where our research equipment is stored. This makes it cost effective and logistically to transport the equipment by truck for installation on the ship.
The ship's home port is also close to many dynamic areas of the ocean near the East coast of the US, which guarantees a wide range of significant wave height conditions. The ocean conditions in coastal waters of the East coast are monitored continuously by NOAA's network of wave rider buoys, which will make up a large part of our ground truth data for the experiment.
The dates are simply dates when the ship was not booked for use and dates during which each member of the NRL research team was available. The experiment was designed to be outside of hurricane season to ensure crew and equipment safety. |
