IR60BH1A radar module is a radar detection module based on the millimeter wave Doppler radar theory, adopts 60G millimeter wave radar technology to realize the non-contact perception of personnel's breathing rate and heart rate. 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 product supports secondary development and adapts to a variety of scenario.
● General UART communication interface, providing general protoco.
● Four groups of I\O are reserved, which can be input and output according to user-defined or simple interface simulatio.
1. Detection of respiration
a) Detection distance：
i. 0.4m≤x≤2m//Detection distance between chest and radar antenna surface
b) Accuracy： ≥90%
2. Detection of heart rate
a) Detection distance：
i. 0.4m≤x≤2m//Detection distance between chest and radar antenna surface
b) Accuracy： ≥85%
3. Perception of presence
a) Detection distance： ≤3m //Distance between antenna surface and personnel
b) Accuracy： ≥90%
4. Detection of movement
a) Motion-triggered
b) Motion direction and position perception
The beam coverage of radar module is shown in. The radar coverage is a three-dimensional sector area with 80 ° horizontal and 80 ° pitch.
Due to the influence of radar beam characteristics, the radar operates far in the normal direction of the antenna surface, 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 action range will be reduced due to the influence of the radar beam range and effective radiation space, which requires additional attention during use.
Based on the radar action mode, the following installation modes are mainly considered:
● Top-mounted
For people that are bedridden or with sleep needs, it is recommended to install on the top: the radar beam is vertically downward facing the human body, and the center of the radar beam is facing the human chest.
In this installation mode, the distance between the radar and the human body to be measured is required to be ≤ 2m
● Oblique-mounted
When the radar is installed obliquely, it needs to be fixed on the wall or beside the bed. The radar is installed obliquely: the radar beam irradiates the human body obliquely, and the center of the radar beam is facing the chest of the human body.
In this installation mode, the radial distance between the radar and the human body to be measured is required to be ≤ 2m.
● Horizontal-mounted
The radar is installed horizontally, and the radar is fixed on the wall or placed on the desktop: the radar beam irradiates the human body in a positive direction, and the center of the radar beam is facing the chest of the human body.
In this installation mode, the radial distance between the radar and the human body to be measured is required to be ≤ 2m.
