nyquist_velocity {bioRad}R Documentation

Nyquist velocity for a given pulse repetition frequency (PRF)

Description

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

radar wavelength in cm

prf1

radar pulse repetition frequency in Hz

prf2

alternate radar pulse repetition frequency in Hz (for a radar opering in dual-PRF mode)

Value

Nyquist velocity in m/s.

Examples

# at C-band (5.3 cm wavelength) and a PRF of 2000 Hz
nyquist_velocity(5.3, 2000)

# extended Nyquist velocity in a dual-PRF scheme
# using 2000 Hz and 1500 Hz PRFs:
nyquist_velocity(5.3, 2000, 1500)
