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 FV-110 ADU.
The separation distance for C-band (4-8 GHz) radars should generally be the same as for
SX-band radars.
