The separation distance for C-band (4-8 GHz) radars should generally be the
same as for X-band radars.
Interference
Even at distances greater than “d min.” in the previous section the radar
might still be able to degrade the performance of the SAILOR FleetBroadband
system.
The presence of one or more X-band radars within a radius up to 100 m could
cause a minor degradation of the signal-to-noise ratio during high speed and
data calls. The degradation will be most significant at high radar pulse
repetition rates.
As long as receiving conditions are favorable, this limited degradation is
without importance. However, if receiving conditions are poor – e.g. due to
objects blocking the signal path, heavy rainfall or icing, low satellite elevation
and violent ship movements – the small extra degradation due to the radar(s)
could cause poor call quality. A voice call might become noisy and perhaps fail
while a data connection might decrease in speed and performance.
