Calculate the Bragg Doppler Angular Frequency

Source: R/SeaSondeRCS.R
seasonder_getBraggDopplerAngularFrequency.Rd

This function computes the Bragg Doppler angular frequencies for a SeaSonde radar system. These frequencies represent the characteristic Doppler shifts due to wave resonance at the Bragg wavelength.

Usage

seasonder_getBraggDopplerAngularFrequency(seasonder_cs_object)

Arguments

seasonder_cs_object

A SeaSondeRCS object containing the necessary data to compute the radar wave number.

Value

A numeric vector of length two, containing the negative and positive Bragg Doppler angular frequencies (in radians per second).

Details

The Bragg Doppler angular frequency \(\omega_B\) is calculated using the formula \(\omega_B = \sqrt{2 \cdot g \cdot k}\) where:

  • \(g\) is the gravitational acceleration (approximately \(9.8 \, m/s^2\)),

  • \(k\) is the radar wave number in radians per meter.

The returned vector contains the negative (\(-\omega_B\)) and positive (\(+\omega_B\)) angular frequencies.
