seasonder_getDopplerSpectrumResolution: Calculate the Doppler Spectrum Resolution

In SeaSondeR: Radial Metrics from SeaSonde HF-Radar Data

Calculate the Doppler Spectrum Resolution

Description

This function computes the Doppler spectrum resolution for a given SeaSondeRCS object. The resolution reflects the frequency difference between consecutive Doppler bins in the spectrum.

Usage

seasonder_getDopplerSpectrumResolution(seasonder_cs_object)

Arguments

seasonder_cs_object

A SeaSondeRCS object containing the necessary data and metadata for Doppler spectrum analysis.

Details

The Doppler spectrum resolution is calculated using the formula: SpectralResolution = SweepRate / NumberOfDopplerCells where:

• SweepRate is the frequency repetition rate of the radar, obtained from the field fRepFreqHz in the object's header.

• NumberOfDopplerCells is the total number of Doppler bins in the spectrum.

This calculation is fundamental for understanding the frequency spacing between adjacent Doppler bins in the radar spectrum.

Value

A numeric value representing the Doppler spectrum resolution in Hertz (Hz).
