People Counting and Tracking Reference Design Using Sub-1GHz Millimeter Wave Radar Sensors

This reference design demonstrates how to use the IWR6843, a single-chip millimeter wave radar sensor from TI with an integrated DSP, to implement indoor and outdoor people counting applications while enabling sub-1GHz wireless communications. This reference design uses the MMWAVEICBOOST and IWR6843ISK evaluation modules (EVMs) and the LAUNCHXL-CC1352R1 wireless MCU LaunchPadTM. The solution is capable of locating people at distances up to 6 meters (close configuration) and 14 meters (long range configuration).

characteristic
