dc.description.abstract | Currently the NOAA Center for Operational Oceanographic Products and Services
(CO-OPS) is transitioning the primary water level sensor at most NWLON stations,
from an acoustic ranging system, to microwave radars. With no stilling well and higher
resolution of the open sea surface, microwave radars have the potential to provide
real-time wave measurements at NWLON sites. Radar sensors at tide stations may
offer a low cost, convenient way to increase nearshore wave observational coverage
throughout the U.S. to support navigational safety and ocean research applications. Here
we present the results of a field study, comparing wave height measurements from four
radar water level sensors, with two different signal types (pulse and continuous wave
swept frequencymodulation-CWFM). A nearby bottomacoustic wave and current sensor
is used as a reference. An overview of field setup and sensors will be presented, along
with an analysis of performance capabilities of each radar sensor. The study includes
results from two successive field tests. In the first, we examine the performance from
a pulse microwave radar (WaterLOG H-3611) and two CWFM (Miros SM-94 and Miros
SM-140). While both types of radars tracked significant wave height well over the test
period, the pulse radar had less success resolving high frequency wind wave energy
and showed a high level of noise toward the low frequency end of the spectrum. The
pulse WaterLOG radar limitations were most apparent during times of high winds and
locally developing seas. The CWFM radars demonstrated greater capability to resolve
those higher frequency energies, while avoiding low frequency noise. The initial field
test results motivated a second field test, focused on the comparison of wave height
measurements from two pulse radar water level sensors, the WaterLOG H3611 and the
Endress and Hauser Micropilot FMR240. Significant wave height measurements from
both radar water level sensors compared well to reference AWAC measurements over
the test period, but once again the WaterLOG radar did not adequately resolve wind
wave energy in high frequency bands and showed a high level of noise toward the low
frequency end of the spectrum. The E+H radar demonstrated greater capability to resolve
those higher frequency energies while avoiding the low frequency aliasing issue observed
in the WaterLOG. | en_US |
