5.1.2. Horizontal installation
As shown in Figure 4, this installation method is mainly orthogonal to human
detection in a standing or sitting position, such as living rooms, home
appliance applications and other occasions.
The radar is recommended to be installed at a height of 1 m to 1.5 m. The
radar is installed horizontally in a positive direction, with an installation angle
of ≤ ±5o and no obvious obstructions or coverings directly in front of the
radar.
The radar normal direction is aligned with the main detection location to
ensure that the main beam of the radar antenna covers the detection area
and that the radar beam covers the human activity airspace.
In this installation mode, the maximum distance for the detection of moving
bodies is L3 ≤ 12 m; the maximum distance for the detection of sitting
bodies/movement is L2 ≤ 5 m and the maximum distance for the detection
of sleeping bodies is L1 ≤ 2.5 m.
The effective range is limited by the radar antenna beam range and deviates
from the radar normal direction. The millimetre wave band has certain
penetrating properties for non-metallic substances, and can penetrate
common glass, wooden panels, screens and thin partition walls, and can
detect moving objects behind coverings; however, it cannot penetrate thicker
load-bearing walls, metal doors, etc.
5.1.3 Tilt mounting
The tilt installation is shown in Figure 5. This installation is mainly for
detecting human movement in a room and is mainly suitable for hotels,
lobbies etc.
The radar installation height is recommended to be 2-2.75m; the tilt angle of
the radar is 10° to 30° with no obvious obstructions or coverings in front of
the radar.
