Original question:

AWR1642:

AWR1642: the problem of obj->numAngleBins

user6124565

Part Number: AWR1642

Hi,

In the srrdemo dss_main.c, the  obj->numAngleBins = SUBFRAME_SRR_NUM_ANGLE_BINS  ,

#define SUBFRAME_SRR_NUM_ANGLE_BINS   (32U)

I am confused by tthe value of SUBFRAME_SRR_NUM_ANGLE_BINS  is equal to 32, why the value is set to 32?

How to get the numAngleBins in the radar system?

Tank you!

    Hi

    This is the size of the angle fft.

    I encourage you to read the mmwave sdk demo documentation. It provides more detail about how the angle fft is computed

    Please see section "Data Path - Direction of Arrival FFT Calculation"

    in file:///C:/ti/mmwave_sdk_02_01_00_04/packages/ti/demo/xwr16xx/mmw/docs/doxygen/html/index.html

    For further information please refer to radar signal processing textbooks.

    I will close this thread.

    thank you
