Nyquist VelocityWhen the radial component of target velocity exceeds one half wavelength (or 180 degrees) the measurement of the phase change between transmitted and received pulses is ambiguous. This results in radial velocity which is aliased. The velocity at which this occurs is the Nyquist Velocity. VN = PRF*λ/4 | |
