Standard 2.0mm slot connectors support SMD patch welding with half holes.

◼ if use SMD patch welding way, pay attention to the module in radar antenna back has components to avoid empty.

6.3. Precautions for radar installation

◼ in motherboard installation position, it is recommended that the following several ways:

1. Try to ensure that the radar antenna is facing the area to be detected, and the antenna is open around without occlusion.

2. To ensure that the radar installation position is firm and stable, the shaking of the radar itself will affect the detection effect.

3, to ensure that there will be no movement or vibration on the back of the radar. Because the radar wave is penetrating, the antenna signal back lobe can be

It picks up moving objects on the back of the radar. A metal shield or a metal backplane can be used for the radar back flap

Shielding to reduce the impact of objects behind the radar.

4. The theoretical range accuracy of radar is the result obtained by special algorithm processing on the basis of the physical resolution of 0.75m. Due to

The range accuracy of the target will fluctuate with different size, state and RCS of the target. And the farthest distances fluctuate a little bit.

◼ in order to meet the performance of on-board antenna, the antenna surrounding prohibited, metal pieces, far away from the high frequency components.

6.4. Installation Environment requirements

This product needs to be installed in a suitable environment. If it is used in the following environments, the detection effect will be affected:

◼ induction of continuous movement in the area of nonhuman objects, such as animals, sustained oscillation of the curtain, is the great strain of the outlet

Green plants, etc.

◼ induction area exists the strong reflector of large area, strong reflector is of the radar antenna can cause interference.

◼ hang wall installation, need to consider the top of the indoor air conditioning, electric fan etc. External interference factors.
