Maximum Unambiguous Velocity (Vmax) vs. PRF
Not only is Rmax dependent on the PRF, but so is the maximum unambiguous velocity (Vmax) that the WSR-88D can determine for a volume of targets. By "unambiguous", we are referring to the WSR-88D's ability to accurately determine the largest Doppler radial velocity with its "first guess" or first pass through the data. The relationship between Vmax and PRF can be expressed mathematically as
PRT = pulse repetition time (s) = 1/PRF and For a PRF = 1000 pulses/sec (or PRT = .001 s) and Next Page: Doppler Dilemma |
