It is also recommended to use threadlocker glue for better lock of screws. Radar
assembly was tested for vibrations and screw locking with Loctite 243 medium strength
threadlocker glue.
In all mounting variants, the Surveillance Radar Sensor should be solid fixed to the
holder and holder should be implemented solid to reduce vibrations and movements of
the device. In case radar is moving or strong vibrations are present on the device false
detections of void targets are possible.
Detection range of the radar is also very dependable on the radar installation. In
general radar can detect targets that are visible to the radar and not in the "radar
shadow" with maximal detection distance proportional to the radar cross section of the
target. For the average single human walking towards the radar detection range of
150m can be achieved when Surveillance Radar Sensor is mounted to the rigid pole 3m
above the ground. Minimal guaranteed distance from the radar where detection is
possible is 3m.
For the best radar operation near field zone around the radar should be clear of
obstacles and objects. It is recommended to have clear zone of minimum 2m around the
radar in all directions and if this is not possible, at least zone in front of radar ±65° in
vertical and horizontal axis and radius of 2m must be clear. If there are obstacles,
especially reflective obstacles in this zone in front of radar this could cause very strong
return of the radio frequency signal to the radar and it could cause saturation of the
input low noise amplifier circuits on the receiver decreasing detection abilities of the
radar significantly.
