5.1.3 Top Mounting
Figure 4 illustrates how it is installed on top. This installation method is typically used to
monitor human bodies (e.g. in a bedroom, nursing home, or hospital bed), determine fall
hazards in wet and slippery environments, and to detect people who are asleep.
In order to ensure adequate coverage of the detection area, the radar installation height
should be set at ≤2.75M, with the horizontal deviation angle set at 3°. There is no
obvious shelter or cover in front of the radar. According to the radar installation height
and radar range, the maximum detection distance of moving human bodies is L3 ~ 6.5m,
that of human sitting/inching is L2 * 3m, and that of human sleeping is L1 ~ 1.8m.
According to radar installation height, radar beam range, and calculation logic of fall
related model, the maximum fall detection distance of human body is L4 ≈ 1.5m.
