Product flow is measured using an active Pulse-Doppler technique.

A pulse-Doppler coherent system is also provided configured for target detection by the method of the invention.

The pulsed Doppler weather radar system reduces ambiguities in measured parameters by staggering at least one pulse of each frame of n pulses transmitted by the radar system.

Directional high- frequency pulsed-wave Doppler measurements can be made with a suitable ultrasonic needle transducers for in vivo measuring of blood flow.

A method and system for SNR enhancement in pulse-Doppler coherent target detection.

A handheld ultrasound instrument (100) is disclosed having enhanced diagnostic modes including pulse/continuous wave Doppler, time-motion analysis, spectral analysis and tissue harmonic imaging.

The Doppler system with impulses makes it possible to collect images radar with very high resolution by all times, making it possible to feed in precise data the inertial platform of Mirage IV.

Mk 24 Foxhunter, Doppler a multifunction radar with impulses with continuation on discontinuous information was manufactured for the new version but knew serious problems and delays.
