3.2.7.2 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 900 VSAT
ADU.
