seasonder_computeBinsRadialVelocity {SeaSondeR} | R Documentation |
Compute Radial Velocities for Doppler Bins
Description
This function calculates the radial velocities corresponding to the Doppler bins in a SeaSondeRCS object, based on the provided Doppler frequencies. The calculation uses the radar's wave number and Bragg angular frequencies.
Usage
seasonder_computeBinsRadialVelocity(seasonder_cs_object, freq)
Arguments
seasonder_cs_object |
A |
freq |
A numeric vector representing the Doppler frequencies for which the radial velocities are to be calculated. |
Details
The radial velocity v
for each Doppler bin is computed using the formula:
v = \frac{\text{Freq} - \text{BraggFreq}}{2 \cdot k_0}
where:
-
\text{Freq}
is the Doppler frequency of the bin. -
\text{BraggFreq}
is the Bragg Doppler angular frequency for the bin. -
k_0
is the radar wave number divided by2\pi
.
The Bragg frequency is negative for bins with frequencies below zero and positive for bins with frequencies above zero.
Value
A numeric vector containing the radial velocities (in meters per second, m/s) corresponding to the provided Doppler frequencies.
