AWR1443BOOST: AWR1443BOOST get the 3D depth image

Part Number: AWR1443BOOST
Other Parts Discussed in Thread: AWR1443

Hello, 

Im currently trying to get the AWR1443 to give me a 3D output.

As long as we don't set the elevation, the radar gives enough points, but as soon as the radar is also asked to give the 3D position the object/points drop to too few amounts. are we missing some key setups?

Second problem we run the AWR1443 with a Nvidia Jetson Tx2, the radar is currently unrecognized. We switched to a Tx1 & we can open/use the radar but the SDK isn't running on the jetson architecture.

    Hello,
    What demo application are you using on your setup ?

    Hi,

    We have an explanation for the reduction in the number of targets when the elevation estimation is enabled. In the 1443, weT use an accelerator to perform the 3D FFT for the elevation calculation.

    The hardware accelerator that we use is quite configurable, and can perform multiple FFTs with a single command (or parameter set). In the demo application, we use a single command to perform the elevation FFT, and associated measurement. However, since, the memory available in the input buffer of the hardware accelerator is limited (to 16K), the number of FFTs it can perform is also limited (to 64).

    Hence when the elevation measurement is enabled, the maximum number of detections is reduced to 64 (from 200 without the elevation measurement).

    There are solutions. You can modify the elevation measurement to run the FFTs twice (or more than twice), so as to increase the number of targets to 128 or more. However, you would have to modify the code for this purpose.

    If you are interested in the programming of the hardware accelerator, you can read its user guide (www.ti.com/.../swra555.pdf)

    Hello,

    Thanks for your answer, could you be more specific on the parameter(s) we need to change the number of FFT to perform.
    We read the doc, and are unsure of what to do (code quote would be appreciated).
