Radar distance
The minimum acceptable separation (d min.) between a radar and the
ADU is determined by the radar wavelength/frequency and the power
emitted by the radar. The tables below show some “rule of thumb”
minimum separation distances as a function of radar power at X and S
band. If the d min. separation listed below is applied, antenna damage is
normally avoided.
“d min.” is defined as the shortest distance between the radar antenna
(in any position) and the surface of the SAILOR 100 GX ADU.
The separation distance for C-band (4-8 GHz) radars should generally be
the same as for SX-band radars.
Radar 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 100 GX
system. The presence of one or more S or X-band radars within a radius
up to 100 m may cause a minor degradation of the Ka-band
connection. The degradation will be most significant at high radar pulse
repetition rates. As long as receiving conditions are favourable, this
limited degradation is not important. 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
X-band (~ 3 cm / 10 GHz) damage distance
