Mounting Requirements
Vibration Specifi cations
Mounting mechanisms shall be designed to be compliant with the radar vibration spectrum illustrated below.
These vibration constraints are based on radio-frequency considerations in order to be compliant with the radar functional specifi cation.
There are no specifi c mechanical requirements along the Y- and Z-axis from a radio-frequency point of view. The mechanical movements
measured at the FLR center along the X-axis shall be less than the peak-to-peak displacement shown below.
Mechanical movement along the X axis shall be less than:
Note:
All values are peak-to-peak.
• 5 Hz < 3 mm
• 10 Hz < 1 mm
• 20 Hz < 0.2 mm
• 30 Hz < 0.05 mm
• Above 40 Hz < 0.03 mm
The spectral density of the peak-to-peak displacement shown above should be measured over 50ms. Also, the spectral density of the
peak-to-peak displacement shall be less than the above-mentioned values divided by 3.
