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)
radar wavelength in cm
radar pulse repetition frequency in Hz
alternate radar pulse repetition frequency in Hz (for a radar operating in dual-PRF mode)
Nyquist velocity in m/s.
# at C-band (5.3 cm wavelength) and a PRF of 2000 Hz nyquist_velocity(5.3, 2000) #>  26.5 # extended Nyquist velocity in a dual-PRF scheme # using 2000 Hz and 1500 Hz PRFs: nyquist_velocity(5.3, 2000, 1500) #>  79.5
