Millimeter-Wave Radar Module FAQs

1) Measure the human falling speed

2) By staying at rest

3) Through the point-cloud imaging

Radar sends and receives electromagnetic waves to determine the existence of the human body.

The closer to the radar, the higher the accuracy.

  • The human body is outside the radar range Please refer to the radar scanning range and adjust the installation angle; the radar measurement range can be different in different environments.
  • Wrong output caused by metal occlusion Too thick office desks and chairs, metal seats, will block the electromagnetic wave penetration, resulting in misjudgment.
  • Scan angle difference Radar did not scan to the trunk cadre position, causing a misjudgment. Phenomenon.
  • Radar sensitivity is too low Radar provides parameter regulation with increased sensitivity improvement.

In normal state, the radar will accurately determine the human body’s sitting state and the presence of sleep, and output information such as falls, breathing, and vital signs.

1.The radar scanning area is large, and movement at the door and next door to the wooden wall is detected. Adjustment method: Reduce the radar sensitivity and the radar provides scene settings.

2.The air conditioner and fan are running directly under the radar.
Adjustment method: Adjust the radar position so that it does not directly face the air conditioner or fan.

3. Object shaking caused by air conditioning wind
Adjustment method: Cotton, non-metallic items will not cause false alarms. Metal objects need to be secured.

4.The radar is not fixed and vibration causes false alarms
Adjustment method: Avoid support shaking and vibration.

5.Occasionally moving objects such as pets and birds
Adjustment method: Since the radar measures micro-movements and has high sensitivity, this interference cannot be eliminated.

6.Power interference, resulting in occasional misjudgments
Adjustment method: Try to keep the power supply current stable and reduce ripple.

The detection range of radar is equivalent to the illumination of a flashlight. Different algorithms and data collection can be implemented under light and shadow.

Although there are signals outside of light and shadow, they can only be used for triggering and cannot be used for algorithm calculations.

Multi-channel radar waves reflect external electromagnetic waves to collect real-time signal changes, output changes in azimuth information such as the distance and angle between the target and the radar in real time, and report points in real time to realize trajectory tracking and multi-person counting functions.

Based on the weak changes in the reflection frequency of radar waves, we can obtain the large-scale movements of the human body’s physiological characteristics in the environment, the micro-movements of the chest, and the weak beating of the heartbeat.

We can calculate the person’s existence in an active resting state, and judge the values ​​related to breathing and heartbeat. In the antenna detection area, the relevant values ​​​​of breathing and heartbeat, sleep and angle position information of the human body are detected in real time.
