  • Page 14: Signal Verification Mode

    Signal verification mode is a feature to output range bin profile. For a basic explanation of how FMCW radar measures distance, see the following link. https://www.infineon.com/dgdl/Infineon-Radar%20FAQ-PI-v02_00- EN.pdf?fileId=5546d46266f85d6301671c76d2a00614 The range bin profile is an array of floating numbers showing the received signal level (in dB) at different distances.

  • Page 15: Measurement Setup

    XENSIV™ 60GHz BGT60TR13C Radar System on Module MCU4 Presence Detection Signal verification mode Measurement setup Put the radar in an open area, to minimize the reflected signal due to other static objects. At 1 m distance, place a corner reflector to maximize the reflected signal at 1 m. The user can then look at the signal level at 1 m to compare the difference with and without plastic casing.

  • Page 16: Anti-Interference

    XENSIV™ 60GHz BGT60TR13C Radar System on Module MCU4 Presence Detection Anti-interference Anti-interference When an environment is using more than one radar module for presence detection, interference may occur and result in a false alarm. The radar module may report a presence event even inside a detection zone. To avoid this issue, the user can set the chirps-per-frame parameter to a higher value (e.g., 16) to enable the radar to check whether interference has occurred or not.
