Abstract
In previous publications, a new echo-ranging Doppler system based
on transmission of repetitive coherent frequency modulated (FM)
sinusoids in two different implementations was presented. One of
these implementations, the Frequency Modulated - frequency shift
measurement (FM-fsm) Doppler system is in this paper compared with
its PW counterpart, the Pulsed Wave - time shift measurement
(PW-tsm) Doppler system. When using transmitted PW and FM signals
with a Gaussian envelope, the parallelism between the two systems
can be stated explicitly, and comparison be made between the main
performance indices for the two Doppler systems. The performance
of the FM and PW Doppler systems is evaluated by means of
numerical simulation and measurements of actual flow profiles. The
results indicate that the two Doppler systems have very similar
levels of performance.
