seasonder_computeCenterDopplerBin: Compute the Center Doppler Bin

In SeaSondeR: Radial Metrics from SeaSonde HF-Radar Data

Compute the Center Doppler Bin

Description

This function calculates the center Doppler bin for a SeaSondeRCS object based on the total number of Doppler bins. The center bin corresponds to the bin representing zero Doppler frequency.

Usage

seasonder_computeCenterDopplerBin(seasonder_cs_object, nDoppler)

Arguments

seasonder_cs_object	A SeaSondeRCS object containing metadata about Doppler bins and other radar parameters.
nDoppler	An integer representing the total number of Doppler bins.

Details

The center Doppler bin is computed as: center\_bin = nDoppler/2 where nDoppler is the total number of Doppler bins. This represents the bin at zero Doppler frequency in a zero-indexed system. Since R uses one-based indexing, users might observe an offset when comparing the output of this function to CODAR's Radia Suite programs.

Value

A numeric value representing the center Doppler bin. The calculation assumes zero-based indexing from CODAR data files, but note that R uses one-based indexing, which may result in differences compared to CODAR's Radia Suite outputs.
