☆ INTRODUCTION


 

The IR24BDA radar module is a radar detection module based on the millimeter wave Doppler radar theory, which achieves human biological motion perception, human biological perception and human breathing detection.This module is based on the enhanced Doppler radar signal processing theory, and achieves wireless perception of the status of personnel in a specific place through the synchronous sensing technology of Doppler parameters of personnel movement and physiological parameters of personnel. It can be tested with our radar test board.(DERADAR-24G).
 
The 32 array antenna form of this module: wide beam radar module. The wide beam radar module is mainly applicable to the top installation mode to realize radar detection in a large angle range; If it is used for horizontal or inclined installation, it is necessary to pay attention to the occlusion of the actual scene in order to realize the radar detection function in a longer range.

☆ DETAILS


 



 

☆ INDUCTION RANGE



The beam coverage of IR24BDA radar module is shown in the figure. The coverage is a 3D fan-shaped area, horizontal 40°, pitching 40°.

 

Note : Affected by the radar beam characteristics, the radar operates far in the normal direction of the antenna plane, but the operating distance deviates from the normal direction of the antenna will become shorter. When the radar is installed on the top or obliquely, the radar is affected by the radar beam range and effective radiation space. The scope of action will be reduced, which needs attention when using.
 
 

 PRECAUTIONS


 

1. Start Time
When the module starts to work when it is initially powered on, it is necessary to completely reset the internal circuit of the module and fully evaluate the environmental noise to ensure the normal operation of the module. Therefore, when the module is initially powered on, it needs a startup stability time of ≥30s to ensure the validity of subsequent output parameters.

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

3. Radar biological detection performance
Because human biological characteristics belong to ultra-low frequency and weak reflection characteristic signals, radar processing requires a relatively long cumulative processing.During the cumulative process, many factors may affect the radar parameters, so occasional detection failure is normal.

4. Power
The radar module requires higher power quality than conventional lowfrequency circuits. When powering the module, it is required that the power supply has no threshold glitches or ripples and that it effectively shields the power supply noise caused by accessory equipment.
 
The radar module needs to be well grounded. Due to the ground noise brought by other circuits, the performance of the radar module may even be reduced or even work abnormally; the most common cause is a shorter detection distance or an increased false alarm rate. In order to ensure the normal operation of the VCO circuit inside the module, the power supply requirement for this module is + 5V- + 6V power supply, voltage ripple≤50mV. The external power supply must provide sufficient current output capability and transient response capability.
 

 

 FAQ


 

1. Interference factors
Radar is an electromagnetic wave detection sensor, and active non-living objects will cause false alarms. The movement of metals and liquids can cause misjudgments. Usually, electric fans, pets close to the radar, and the shaking of metal curtains will cause misjudgments. Radar needs to be planned from the perspective of installation.
 
2. Non-interference factors
Radar electromagnetic waves can penetrate human clothing, curtains, veneer, and glass. It is necessary to determine the installation angle and performance of the radar according to the application.
 
3. Semi-interference factor
The radar judges the presence of a human body and is not suitable for directly facing the air conditioner. The motor inside the air conditioner can cause the radar to misjudge. Radar products can not directly face the air conditioner. It can be the same direction as the air conditioner.
