Main working properties 4.1 Radar module operating range The beam coverage of the radar module is shown in the figure below.
Due to the characteristics of the radar’s beam, it has a long-range coverage in the direction normal to the antenna surface but a short-range if it deviates from the normal direction of the antenna surface. In addition, when the radar is mounted on top or inclined, its range will be reduced. This is due to the influence of its beam and effective radiation space. This should be put into consideration during usage. 4.2. main functions and performance 1. Main functions and performance a.
Radar installation height is h=2.4m ~ 3M. With a radius of radar beam coverage area of R within the radar projection area, it is possible to further divide the projection area into areas for fall detection, presence detection, and motion detection. The Figure below illustrates a schematic diagram of the area. (a) Radar projection schematic (b) Schematic diagram of beam splitting 5.2. Tilt mounting mode Certain scenarios require the radar to be installed obliquely, such as in a corner.
6. Typical applications 1. The product is appropriate for small-area scenes, including those in the bathroom, the bedroom, and the living room. 2. It is suitable for both inclined and top mounting. 3. The product is suitable for single or double occupancy. 4. The product must eliminate interference actions in consideration of application scenarios.
