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 Satellite TV ADU.
The separation distance for C-band (4-8 GHz) radars should generally be the same as
for S-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 Satellite TV 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 Ku-band reception. The degradation will be most
significant at high radar pulse repetition rates.
