Calculate Nyquist velocity for a given pulse repetition frequency (PRF)

Source: R/nyquist_velocity.R

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)

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
