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.
Usage
nyquist_velocity(wavelength, prf1, prf2)
Arguments
- wavelength
Numeric. Radar wavelength, in cm.
- prf1
Numeric. Radar pulse repetition frequency, in Hz.
- prf2
Numeric. Alternate radar pulse repetition frequency for a radar
operating in dual-PRF mode, in Hz.
Value
Nyquist velocity, in m/s.
Examples
# Get Nyquist velocity at C-band (5.3 cm wavelength) and a PRF of 2000 Hz
nyquist_velocity(5.3, 2000)
#> [1] 26.5
# Get extended Nyquist velocity in a dual-PRF scheme using 2000 Hz and
# 1500 Hz PRFs
nyquist_velocity(5.3, 2000, 1500)
#> [1] 79.5
