5.3.Detection range test
The test methods for radar triggering and maintaining detection range are introduced as follows:
-
Trigger scope:
The target human body approaches the radar from a distance when the radar reports that there is no one there. When the radar starts to report that there are people, it stops moving forward. The current position is
The boundary of the radar trigger detection range; the area enclosed by the detection boundaries in all directions is the radar trigger detection range.
-
Keep range:
The target human body maintains small movements at the position to be tested when the radar reports that there are people, such as shrugging and raising hands. If the radar detects within 60 s
If there are people being reported all the time, the current position is within the detection range of the radar; otherwise, the detection position is outside the detection range.
