Calculate Radial Velocity Resolution
Description
Computes the radial velocity resolution for a SeaSonde radar cross-section (CS) object. This measurement indicates the smallest change in velocity that the radar can discern between different targets or scatterers within its observation area. The calculation is based on the Doppler spectrum resolution and the radar wave number, providing a crucial parameter for analyzing the radar's capability to distinguish between velocities.

Details
The radial velocity resolution v_{res}
is determined using the formula:
v_{res} = \frac{\text{SpectraRes}}{2 \cdot k_0}
where v_{res}
is the radial velocity resolution, \text{SpectraRes}
is
the Doppler spectrum resolution, and k_0
is the radar wave number divided
by 2\pi
. This formula reflects the relationship between the
frequency resolution of the radar's Doppler spectrum and the corresponding
velocity resolution, taking into account the wave number which is a fundamental
characteristic of the radar system.
Value
A single numeric value representing the radial velocity resolution in meters per second (m/s), indicating the radar's ability to differentiate between closely spaced velocities.
