Linux/AWR1642: how to identify the number of range and doppler bins

Ashish Karel
Prodigy 160 points
Part Number: AWR1642

Tool/software: Linux

I am using uart port to get my raw data for my detections, my current code works fine to provide positions and their velocites.

But for some requirement of my work i need the doppler heat map and visualise it the same like in the mmwave demo visualizer but using my own script !

But the thing is i dont know what my range and doopler bins value are , to calculate size of the doopler 2d matrix i.e  "Size= #RangeBins *#DopplerBins * 4 bytes".

Can anyone please guide me through this and how can i visualize this heat map does it require some preprocessing steps?

Thanks,

Ashish

    Hi,

    First step is to make sure that you are computing on target the information needed.

    Second step is to make sure that you have sufficient time to send this data through the UART.

    Third step is to choose the visualization tool (matlab, gui composer , qt based gui ...)

    Thank you
