IWR1642: Material Reflectivity

user5812271
Intellectual 370 points
Part Number: IWR1642

Hi,

I am trying to determine the device's sensitivity to different materials. Running the High Accuracy mode, I have tried conducting experiments where I set up objects made of copper, aluminum, and PVC at varying distances and see which one the device registers as an "object"--but I have not been able to obtain consistent results. Is it perhaps not a question of the material's reflectivity to mm-waves? Do the objects' surface area relative to each other matter? 

Regards,

Josh

    Hello Josh,

    Please refer to below applications page, you will find various objects detected at various ranges.
    www.ti.com/.../applications.html

    Also Refer to mmWave Radar Sensors: Object Versus Range application note
    www.ti.com/.../swra593.pdf

    This is a qualitative gauge for the possibilities of range detection using TI mmWave sensors.
    However, for specific end applications, the detectable range will differ and be influenced by radar system parameters, target characteristics, and
    background effects (clutter, noise, and more).

    For more details, you could refer to "Programming Chirp Parameters in TI Radar Devices" application note from the below location:
    www.ti.com/.../swra553.pdf

    Thanks and regards,
