5.1.3. Top-mounted
As shown in Figure 4, it is installed on the top. This installation method is
mainly aimed at slippery areas where there is a risk of falling (e.g. toilet,
kitchen, etc.) human body monitoring under peaceful lying state (e.g.
bedroom, nursing place, hospital bed, etc.).
The radar shall be installed vertically, and the horizontal deviation angle
shall be ≤ 3 °, so as to ensure that the main beam of the radar covers the
detection area; The recommended installation height of radar is ≤ 2.75m;
There is no obvious shelter or cover in front of the radar.
Affected by the radar installation height and radar beam range, in this
installation mode, the maximum detection distance of active human body is L3 ≈
6.5m; The maximum distance of human sitting / slight motion detection is L2 ≈
3M.

Note：
A. For the above different installation methods, the main radar beam needs to
cover the main activity area of the human body and face the normal direction as far
as possible；
B. When installed obliquely, the horizontal action distance will be reduced due to
the change of horizontal projection of the coverage area；
C. When the module is working, the module surface should not be covered by metal
objects；
D. Affected by the transmission characteristics of electromagnetic wave, the radar range is
related to the target RCS, the material and thickness of the target cover. The effective
range of radar will change to a certain extent;
