ECHANICAL INSTALLATION
4.1 I
NSTALLATION
In order to properly install the SR radars and integrate it into an active, efficiency
protection system, it is imperative that the user will first understand some basic rules
regarding radars in general and specifically regarding the SR radars. Prior to sensor
installation it is imperative that the user reads the following list of limitations and
restrictions and ensures that the intended installation site is suitable for installation.
When in doubt please consult with Magos representatives.
The following limitation and restriction should be considered prior to installation:
● Environment: Radars are based on line-of-sight detection. Any obstacles hiding
or partially hiding areas from the radar will not be properly protected. This
include obvious obstacles such as walls, buildings, hills etc, but also includes
less obvious obstacles such as light foliage, low bushes etc., where target is
only partially obscured from the radar. In such case detection performance is
reduced.
● While the SR radar features "zero-doppler" detection, maximum detection
ranges for tangent moving targets (moving targets that remain at a constant or
near constant distance from the radar) or for crawlers are typically reduced
compared to radial moving targets. This occurs in areas that are not clear of
obstacles such as bushes, trees and other vegetation.
● The SR radar does not implement target classification – which means that cars,
human walker large animals and sometimes small animals are all declared as
targets.
● The SR's instrumental resolution in azimuth is ~5°, and in range it is ~0.4m.
Therefore target separation capabilities are ~1m in range and 7° in azimuth. This
means that two or more targets moving within less than 1m difference in range
from each other and less than 7° will be declared as single target, and the
reported location will be near the center of the group. Note that for single target
location accuracy is much better than resolution, and reach less than 1° in
azimuth and approximately 0.1m in range.
● As mentioned earlier the SR series might exhibit disturbances and "ghost"
targets as a result of large returned signals. This occurs when a very large target
(car/ truck etc.) moves in the vicinity of the radar (30m away or less, and 5m
away or less for human targets) even outside the stated coverage area.
Therefore it is recommended to install the sensor in unpopulated, isolated spots
(or alternatively use high poles to distance the radar from ground movement).
