Figure 5 illustrates an inclined installation. Generally, this installation method is intended
to detect movement in a room and is primarily applicable to hotels, halls, and other
public spaces.
The recommended installation height of the radar is 2 - 2.75m; The radar's downward
inclination angle range is 10 - 30 degrees, and there is no obvious shelter or cover in
front of the radar.
The normal direction of the radar is aligned with the radar's main detection area to
ensure the radar antenna's main beam covers the detection area and the radar beam
covers the human activity airspace.
This installation mode allows the maximum detection distance of a moving human body,
denoted as L3, to be about ~7 meters; while the maximum detection distance for human
sitting and inching, denoted as L2, is ~4 meters, and the maximum detection distance
for human sleep L1 is ~ 3 meters.
When operating in this mode, there may be a blind area under the radar and adjacent to
it. As the dip angle increases, the detection distance of the static human body will be
significantly reduced. Depending on the radiation characteristics of the radar antenna,
the range of the radar will be reduced if it deviates from the normal direction of the radar.
