mmWave radar detection of person presence up to 9m
This 24GHz radar sensor uses FMCW and CW multi-mode modulation as well as a separate transmitter and receiver antenna structure. In operation, the sensor first emits FMCW and CW radio waves into the detection area. Subsequently, the radio waves that are reflected by all targets that are moving, micro-moving or weakly moving in the area. They are converted into electrical signals by the millimeter wave MMIC circuit in the sensor system. Afterwards, these signals are sent to the processor and processed through the corresponding signal and data algorithms. The millimeter wave radar can detect the presence of humans, stationary and moving persons within the detection range. Moreover, it can even detect static or stationary human presence such as a sleeping person. There are two ways to output the detection result: Serial interface and I/O port. Moreover, the sensor module is characterized by high detection reliability, high sensitivity, small size and easy use or integration into applications.
