Convert Doppler Bins to Normalized Doppler Frequency

Source: R/SeaSondeRCS.R
seasonder_Bins2NormalizedDopplerFreq.Rd

This function retrieves the normalized Doppler frequencies corresponding to the specified bins in a given SeaSondeR object.

Usage

seasonder_Bins2NormalizedDopplerFreq(seasonder_cs_object, bins)

Arguments

seasonder_cs_object

A SeaSondeR cross-spectral object containing Doppler bin metadata.

bins

A numeric vector specifying the Doppler bin indices.

Value

A numeric vector of normalized Doppler frequencies corresponding to the specified bins.

Details

This function first retrieves the Doppler bin frequencies in normalized form using seasonder_getDopplerBinsFrequency. It then selects the normalized Doppler frequencies corresponding to the specified bin indices.

Normalized Doppler Frequency Calculation: The normalized Doppler frequency is typically defined as: $$f_{norm} = \frac{f_{doppler}}{f_{bragg}}$$ where:

  • \(f_{norm}\) is the normalized Doppler frequency,

  • \(f_{doppler}\) is the Doppler frequency of a given bin,

  • \(f_{bragg}\) is the Bragg frequency, computed based on radar wavelength.
