radarisüsteem, mis määrab impulsi ajastamise tehnika abil sihtmärgi kauguse ja kasutab tagastatud signaali Doppleri efekti sihtobjekti kiiruse mõõtmiseks
radar system that determines the range to a target using pulse-timing techniques, and uses the Doppler effect of the returned signal to determine the target object's velocity
Impulssdoppleriraadiopeiler on aluseks sünteetilise apertuuriga radarile, mida kasutatakse radarastronoomias, kaugseires ja kaardistamises. Lennuliikluse juhtimises kasutatakse seda peilerit õhusõidukite eristamiseks soovimatutest kajaallikatest, nn segakajast. Lisaks eelnimetatud tavapärastele seirealastele rakendustele on Impulssdoppleriraadiopeiler leidnud edukat kasutust ka tervishoius, nt kukkumisohu hindamisel ning kukkumiste tuvastamisel, olles abiks nii hooldus- kui ka kliinilises tegevuses.
Good to know
Impulssdoppleriraadiopeiler ühendab impulssraadiopeilerite ja pidevlainepeilerite omadused, mis olid varem elektroonika keerukuse tõttu eraldatud.
Pulse-Doppler radar is the basis of synthetic aperture radar used in radar astronomy, remote sensing and mapping. In air traffic control, they are used for discriminating aircraft from clutter. Besides the above conventional surveillance applications, pulse-Doppler radar has been successfully applied in healthcare, such as fall risk assessment and fall detection, for nursing or clinical purposes.
Good to know
Pulse-Doppler radar combines the features of pulse radars and continuous-wave radars, which were formerly separate due to the complexity of the electronics.
