The mmWave Fall Detection Radar Sensor Module is a self-contained module near distance sensor based on Infineon mmWave FMCW industrial radar operating at 24GHz. The unit is built with the enhanced Doppler radar signal processing mechanism and standard algorithm which enables distinguishing between the occupied and unoccupied conditions and identifying human activities in a self-adaption environment, especially human falling.
There is a two-array, high-performing antenna built on the module and it has fan-beam pattern beamwidth where the horizontal is 90° and vertical is 60° which makes its sensing area as high as 20m2.
