«Spectre de réponse au choc» est un terme générique. Pour que sa signification soit spécifique, il est nécessaire d'ajouter un qualificatif, par exemple spectre de réponse au choc en accélération, en vitesse ou en déplacement.  1, fiche 2, Français, - spectre%20de%20r%C3%A9ponses%20au%20choc

As you probably know, the GHRS automatically corrects observations for the effects of the motion of the HST spacecraft. This correction is done in real time as an exposure is in progress. Every minute a new shift is calculated and if necessary a change in the deflection of the spectrum is made. These onboard corrections cannot be removed after the fact except as an overall shift of the spectrum, but the net doppler compensation applied is stored in the data header. As in the case of a heliocentric correction to radial velocity, the doppler compensation is calculated from the position of the object relative to the vector of motion of the spacecraft.  3, fiche 4, Anglais, - Doppler%20effect%20compensation

Record number: 4, Textual support number: 2 CONT

Probably an automatic Doppler effect compensation is used: when approaching the object, the questioning signal becomes shorter and the impulse sequence faster. The sound volume can also be varied in order to detect more distant objects or sound-absorbing objects.  1, fiche 4, Anglais, - Doppler%20effect%20compensation

The Next Generation Weather Radar system(NEXRAD) comprises approximately 160 Weather Surveillance Radar-1988 Doppler(WSR-88D) sites throughout the United States and selected overseas locations. This system is a joint effort of the United States Departments of Commerce(DOC), Defense(DOD), and Transportation(DOT). The controlling agencies are the National Weather Service(NWS), Air Weather Service(AWS) and Federal Aviation Administration(FAA), respectively. Level II data are the three meteorological base data quantities : reflectivity, mean radial velocity, and spectrum width. From these quantities, computer processing generates numerous meteorological analysis products known as Level III data. Level II data are recorded at all NWS and most AWS and FAA WSR-88D sites. Level III products are recorded at the 120 NWS sites. The data are sent to the National Climatic Data Center(NCDC) for archiving and dissemination.  3, fiche 5, Anglais, - next%2Dgeneration%20weather%20radar%20system
