seasonder_getBraggDopplerAngularFrequency: Calculate the Bragg Doppler Angular Frequency

In SeaSondeR: Radial Metrics from SeaSonde HF-Radar Data

Calculate the Bragg Doppler Angular Frequency

Description

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.

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.

Value

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