R/nyquist_velocity.R
nyquist_velocity.Rd
Calculates the Nyquist velocity given a radar's pulse repetition frequency (PRF) and wavelength. When specifying two PRFs, the extended Nyquist velocity is given for a radar using the dual-PRF technique.
nyquist_velocity(wavelength, prf1, prf2)
wavelength | radar wavelength in cm |
---|---|
prf1 | radar pulse repetition frequency in Hz |
prf2 | alternate radar pulse repetition frequency in Hz (for a radar operating in dual-PRF mode) |
Nyquist velocity in m/s.
