5.1.2. Inclined-mounted
As shown in Figure 5, it is installed obliquely. The installation method mainly
detects the movement of people in the room, which is suitable for hotels, halls
and other places.
The recommended installation height of radar is 2-2.75m; The downward looking
tilt angle range of the radar is 10 ° ~ 30 °, and there is no obvious shelter and
cover in front of the radar.
The normal direction of the radar is aligned with the main detection position to
ensure that the main beam of the radar antenna covers the detection area and
the radar beam covers the airspace of human activities.
In this installation mode, the maximum detection distance of moving human
body is L3 ≈ 7m; The maximum distance of human sitting /slight motion detection
is L2 ≈ 4m.
In this mode, there may be a surveillance blind area directly below the radar and
adjacent areas. With the increase of downward viewing angle, the detection distance
of stationary human body will be significantly compressed.
Affected by the radiation characteristics of radar antenna, the effective range of
radar will be reduced if it deviates from the normal direction of radar.
