Page 3: Overview
1. Overview The MR60FDA1 radar module is a radar module that uses 60G millimeter wave radar technology for human movement and posture sensing, and thus for fall detection. The module is based on the FMCW radar system and enables the wireless sensing of the status of people in a specific location. This radar module has the following operating characteristics. -

Page 7: Main Functions And Performance
Due to the characteristics of the radar beam, the radar acts farther in the direction normal to the antenna face, but the distance away from the antenna normal becomes shorter. When the radar is mounted on top or at an angle, the radar range will be reduced due to the radar beam range and the effective radiation space, which needs to be taken into account when using the radar. -

Motion detection functions Motion triggering Motion direction and position sensing 5. How the radar works and how it is installed 5.1. vertical mounting mode The radar is mounted on the roof and is directed vertically downwards. The radar is installed at a height of H = 2.4 m to 3 m; the radius of the radar beam coverage area is R. -
Page 9: Horizontal Mounting Mode
For this type of installation, a gyroscope sensor is considered to be located at home on the radar for radar tilt measurement, which in turn assists the radar with angle correction. 5.3. Horizontal mounting mode Given the current number of channels in the radar chip, the fall check function in horizontal mounting mode is not considered for the time being.
