System and method for acoustic Doppler velocity processing with a phased array transducer including using a wide bandwidth pulse transmission to resolve ambiguity in a narrow bandwidth velocity estimate
System and method for acoustic Doppler velocity processing with a phased array transducer including using a wide bandwidth pulse transmission to resolve ambiguity in a narrow bandwidth velocity estimate
A system and method for measuring velocity in a fluid medium utilizing a measuring system are disclosed, wherein the measuring system comprises a transducer. In one aspect, the method comprises transmitting a first set of one or more signals of a bandwidth substantially broader than the bandwidth of the measuring system, receiving echoes from the first set of signals, obtaining a first velocity estimate based at least in part on the echoes from the first set of signals, transmitting a second set of one or more signals of a bandwidth, substantially equal to, or narrower than the bandwidth of the measuring system, receiving echoes from the second set of signals, obtaining two or more possible velocity estimates based at least in part on the echoes from the second set of signals, and selecting one of the possible velocity estimates based on the first velocity estimate.
