seasonder_NormalizedDopplerFreq2DopplerFreq {SeaSondeR} | R Documentation |
Convert Normalized Doppler Frequencies to Doppler Frequencies
Description
This function converts normalized Doppler frequencies into their corresponding Doppler frequencies (in Hz) within a SeaSondeR
object.
Usage
seasonder_NormalizedDopplerFreq2DopplerFreq(
seasonder_cs_object,
doppler_values
)
Arguments
seasonder_cs_object |
A |
doppler_values |
A numeric vector specifying the normalized Doppler frequencies to be converted into Doppler frequencies (Hz). |
Details
The function follows these steps:
Calls
seasonder_NormalizedDopplerFreq2Bins
to convert the input normalized Doppler frequencies into Doppler bin indices.Calls
seasonder_Bins2DopplerFreq
to obtain the corresponding Doppler frequencies in Hz.
The relationship between the normalized and absolute Doppler frequencies is defined 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.
Value
A numeric vector of Doppler frequencies (in Hz) corresponding to the input normalized Doppler frequencies.
