Abstract
A velocity deception apparatus utilizes a serrodynable digital phase shifter of the Schiffman type where each cell of the phase shifter is driven by an output of a multi-bit counter whose clock input in turn is driven by a voltage-to-frequency converter which has a pulse train output which responds substantially instantaneously to the analog value of a linear or second order function which produces the desired frequency translation. In practice, this performs as a velocity gate stealer which produces slowly changing false doppler frequencies.
