<div class="definition"><div class="short_definition">The maximum range of [[radial velocity]] that can be observed  without ambiguity by a [[Doppler radar]], [[sodar]], or [[lidar]].</div><br/> <div class="paragraph">Velocities outside this interval are folded into the interval. For a [[pulsed radar]] or sodar operating  with an [[interpulse period]] ''T,'' or a lidar with an [[A/D converter]] sampling interval ''T,'' the [[unambiguous  velocity interval]] is -&lambda;/4''T'' to +&lambda;/4''T'', where &lambda; is the operating [[wavelength]]. This interval  can be extended by the use of dual [[PRF]] and other techniques. <br/>''See'' [[velocity aliasing]], [[Nyquist  frequency]].</div><br/> </div>
