The design of radar signals having both high range resolution and high velocity resolution

Radar systems that yield simultaneous information regarding the range and velocity of a target would be useful in certain applications. A discussion is presented of some fundamental limitations on simultaneous range-velocity determination in terms of ambiguity diagrams, with the aid of a quantum mechanical analog to the Wigner distribution function. A sequence of signals is found in which the signals yield both range and velocity information with increasing accuracy. However, this desired property is not accompanied by a waveform suitable for maximum operating efficiency.
