seasonder_DopplerFreq2NormalizedDopplerFreq {SeaSondeR} | R Documentation |
Convert Doppler Frequencies to Normalized Doppler Frequencies
Description
This function converts Doppler frequencies (in Hz) into their corresponding normalized Doppler frequencies within a SeaSondeR
object.
Usage
seasonder_DopplerFreq2NormalizedDopplerFreq(
seasonder_cs_object,
doppler_values
)
Arguments
seasonder_cs_object |
A |
doppler_values |
A numeric vector specifying the Doppler frequencies (in Hz) to be converted into normalized Doppler frequencies. |
Details
The function follows these steps:
Calls
seasonder_DopplerFreq2Bins
to convert the input Doppler frequencies into Doppler bin indices.Calls
seasonder_Bins2NormalizedDopplerFreq
to obtain the corresponding normalized Doppler frequencies.
The normalized Doppler frequency is computed as:
f_{doppler} = f_{norm} \times f_{bragg}
where:
-
f_{doppler}
is the Doppler frequency in Hz, -
f_{norm}
is the normalized Doppler frequency, -
f_{bragg}
is the Bragg frequency, computed based on radar wavelength.
This function ensures consistency by mapping input frequencies to their closest bin representation before normalization.
Value
A numeric vector of normalized Doppler frequencies corresponding to the input Doppler values.
