Major function

Radar operating range
The beam coverage range of the radar module is shown in Figure 3.
The radar covers a three-dimensional sector area of horizontal 60 and pitch 60.

Affected by the beam characteristics of radar, the action distance of radar in the normal direction of the antenna surface is relatively far, but the action distance deviated from the antenna normal direction will become shorter. When the radar is tilted, the action scope of the radar will decrease due to the radar beam range and effective radiation space, so attention should be paid to when using.

Radar operation and installation method

Installation
This radar module recommends tilt installation and a distance of 1.5 m parallel to the scanning surface。

Slant installation
For the demand of sleep breathing and heartbeat detection, the radar should be installed tilted (as shown in Figure 5). The radar should be installed 1m directly above the bed and tilted 45 between the bed. The distance between the radar and the chest cavity is within 1.5m to ensure that the radar can normally detect breathing, heartbeat and sleep-related parameters. The radar normal direction is aligned with the main detection position to ensure that the main beam of the radar antenna covers the human sleep detection area land within certain boundaries.

The radar normal direction is aligned with the main detection position to ensure that the main beam of the radar antenna covers the human sleep detection area land within certain boundaries.

Limited by the beam range of the radar antenna, the effective action distance of the radar normal direction will be reduced.
Millimeter wave frequency band electromagnetic wave has certain penetration properties for non-metallic substances, which can penetrate common glass and wood Plate, screens and thin partition walls can detect moving objects behind the shelter; but for thicker load-bearing walls, Metal doors, etc., do not penetrate.

Operating mode of the radar
After the radar module passes the statistical analysis and processing, the personnel status of the current detection area is comprehensively evaluated, and the user can directly use the result.

Real-time operation mode

In this mode, the radar module periodically gives the existence and movement states of personnel in the current radar detection area. The main states include:

1. Detect there is anyone in the room；
2. Measure people’sHeart rate and respiratory rate；
   In this mode, for the accuracy of the environmental state judgment, the state output logic of the radar module is as follows:
   A. Only when the radar equipment detects the status change, it has the corresponding status output of the radar; otherwise, the radar remains silent;
   B. The radar switch from unmanned to manned (motion, approach, away) is a fast switching state, and the switching time is 1s;
   C. If the radar switches from manned to unmanned, it needs to be confirmed many times and the switching time is 1 minute;
   D. Radar collects the breathing/heart rate frequency and breathing/ heart rate signal state during the dynamic and static human body in real time. The breathing heart rate frequency refresh frequency is 3s, and the signal state changes and output;

Sleep detection mode

In this mode, the module periodically gives the sleep status and breathing rate of the personnel in the current radar detection area, and the main states include

1. Sleep quality assessment: awake, deep sleep, light sleep;
2. Bed-in / off-the-bed judgment;
3. Statistics of respiratory / heart rate frequency
4. In sleep detection mode, the radar module has a specific safety for the accuracy of sleep-related state judgment Installation mode and installation height limit;
   The radar should be installed at 1m height directly above the head of the bed, and tilted downward to 45 pairs in the middle of the bed, to ensure that the distance between the radar and the human body is within 1.5m, and to ensure that the radar detection range can normally cover the sleep area.

Typical application mode

This module is mainly used in scenarios such as health management or home enabling. The following explains the application mode of typical scenarios.

Bedroom installation and application
For specific applications, real-time relevant information about bedridden personnel, such as human / unmanned, sleep state, sleep depth, exercise information, etc., and then give relevant information to achieve specific applications. In this mode, the radar needs to be top-mounted. Based on this mode of application, the application can be implemented including.

• Elderly care
• Health care
• Smart home
• Family health

Healthy life application

Based on the detection characteristics of the sleep state and breathing rate of the sleepers, the radar can be better used in a healthy life, including:

• Intelligent health single product linkage application
• Household electrical appliances

Attentions

Start time
Because the module needs to completely reset the internal circuit of the module, and the environmental noise is fully evaluated, to ensure the normal operation of the module.
Therefore, when the module is initially powered up, the startup stabilization time needs 30s to ensure the effectiveness of the subsequent output parameters.

Respiratory and heartbeat detection scene limitations
Radar is a non-contact device, and the respiratory and heartbeat detection of the target needs to lock the position of the target first Then, the respiratory and heartbeat intensity and value of the target were collected and calculated.
Therefore, the detection target is required to maintain a resting state for detection within a reasonable detection range, so as to avoid the continuous motion affecting the locking of the radar to the target, thus affecting the detection of breathing and heartbeat.

Effective detection distance
The detection distance of the radar module is closely related to the target RCS and environmental factors, and the effective detection distance may change with the change of the environment and the target. This module does not have the ranging function temporarily, so it is normal for the effective detection range to fluctuate in a certain range.

Radar biological detection performance
Because human biometric features are ultra-low frequency and weak reflection characteristic signals, radar processing needs a relatively long time of accumulation processing. In the accumulation process, many factors may affect radar parameters, so the accidental detection failure is a normal phenomenon.

Power
The radar module has higher power quality requirements than conventional low- frequency circuits. When powering the module, electricity is required The source has no threshold burr or ripple phenomenon, and effectively shields the power supply noise caused by the accessory equipment. Radar module needs good grounding, and the ground noise caused by other circuits may also cause the radar module performance decline or even abnormal operation; the most common is that the detection distance is approaching or the false alarm rate increases. To ensure the normal operation of the VCO circuit inside the module, the power supply requirement for this module is + 5V~+5.5V Electric, voltage ripple of 100mV. External power supplies must provide sufficient current output capacity and transient responsiveness
