In addition to the block outputs listed above, the block saves spectral and time-series data to
CDIP formatted files, and offers an option to log the outputs in record format.
Description
The purpose of the block is to process the acquired Sutron Radar Water level data to determine
the wave energy spectrum, wave height parameters. The data is collected once a second for
2048 seconds (34 minutes 8 seconds). The data is then processed using industry standard
algorithms to produce the mean period, significant wave height, max wave height, zero-up
crossing period, peak wave period and spectrum vector.
The processing includes the following steps:
1.
Capture 2048 samples of radar data
2.
Verify the data quality for any missing data. If there are holes in the data, fill them up
using interpolation.
3.
Apply detrending filter on the data and obtain final time-domain data.
4.
Compute the ensemble-averaged spectral estimate using FFT techniques.
5.
Compute the frequency vector.
6.
Use wave estimator functions on the spectral estimates and frequency vectors to compute
the final output values.
Configuring the WavProc Block
The following section describes how the Xpert WavProc block is set up for Wave height
parameter estimation.
