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, fiche 2, Anglais, - fine%20beam

Les faisceaux en mode fin sont destinés aux applications qui requièrent de hautes résolutions spatiales et de plus faibles couvertures. Les faisceaux fins couvrent les angles d'incidence de 30° à 50°. Ce type de faisceau sera disponible en co-polarisation, en polarisation croisée, en double-polarisation ou en mode polarimétrique.  2, fiche 2, Français, - faisceau%20fin

Optical Head(OH). The OH is typically located outside the spacecraft and performs the critical functions of generating and pointing the transmit laser beam and acquiring and tracking the received beacon and receive laser beams. Major elements of the OH are :-Coarse pointing assembly used for steering the terminal line of sight.-Optical subsystem comprising telescope, optical bench and beacon collimator.-Fine pointing assembly(FPA) : This is a mechanism used in conjunction with the tracking sensor to provide the tracking function for the terminal.-Point ahead assembly(PAA) : This is similar to the FPA and is used to introduce the required point ahead offset to the transmit beam.-Acquisition sensor(AS) : This is a wide field of view sensor used during acquisition for the identification and location of the partner terminal.-Tracking sensor(TS) : This is a fast sensor that operates in a closed loop with the FPA.  2, fiche 3, Anglais, - point%2Dahead%20assembly
