Fine Beam. The fine beam mode is intended for applications which require the best spatial resolution available from the RADARSAT system. The azimuth resolution is 8. 4 m, with range resolution 9. 1 m to 7. 8 m from F1 to F5. Since the radar operates with a higher sampling rate in this mode than in any of the other beam modes, the ground swath coverage has to be reduced to a nominal 50 km in order to keep the downlink signal within its allocated bandwidth. Originally, five fine beam positions, F1 to F5, were available to cover the far range of the swath, the incidence angle range from 37 to 47 degrees. By modifying timing parameters, 10 new positions have been added with offset ground coverage. Each original fine beam position can either be shifted closer to or further away from Nadir. 2, record 7, English, - fine%20beam

Le terme «échantillonnage» est toujours employé lorsqu'une carte sonore est utilisée. Il désigne en règle générale l'enregistrement de sons provenant d'une source quelconque. Étant donné que les sons doivent être numérisés, l'échantillonnage est un procédé d'enregistrement particulier. Par exemple, lorsque des sons sont enregistrés à l'aide d'un micro, le signal acoustique est transformé en oscillations électriques. Pour enregistrer sous une forme numérique des vibrations analogiques, celles-ci doivent être échantillonnées. La valeur mesurée lors de la réception est enregistrée, puis c'est au tour de la valeur suivante, et ainsi de suite. 1, record 9, French, - %C3%A9chantillonnage

An ambiguity in the frequency represented by sampled seismic data. Where there are fewer than two samples per cycle, an input signal at one frequency yields the same sample values as, and hence appears to be, another frequency at the output of the system. Half of the frequency of sampling is called the "folding" or "Nyguist" frequency, fN;a frequency larger than this, fN+Y, appears to be the smaller frequency, fN-Y. The two frequencies are "aliases" of each other. 2, record 18, English, - alias
