AWRL6432: SDK 5.4 Motion presence,example

Prodigy 20 points
Other Parts Discussed in Thread: AWRL6432
  • Part Number: AWRL6432

Tool/software:

I am working  on  5.4 sdk motion presence detection example using AWR6432 board with Range-azimuth pipeline in which there is limitation to increase angle accuracy for both elevation and azimuth due to memory limitation in HWA.Could you please let me know is any way or any chirp configuration to improve the same 

Thanks in advance

    Hey Lakshmi,

    Angular resolution is largely limited by the number of antennas or the angle-of-arrival (AoA) algorithm utilized. Since we can't expand beyond 3x2, we can only utilize different AoA algorithms to improve resolution. For example, for high accuracy applications such as In-Cabin Life Presence Detection (LPD), we utilize Capon 2D angle spectrum generation to create a finer resolution range-azimuth-elevation heatmap. This does require more processing time - and power - over the simpler FFT based approach though.

    I would recommend taking a look at the LPD project shared above to get an idea of how Capon is used, but let us know if you have any other questions.

    Cheers,

    Kristien
