IWR6843ISK: Range profile in Output Packet

Kai Yang1

Part Number: IWR6843ISK

In the out of box demo, the sensor outputs the Range profile TLV as the integer in all the range bins. I would expect the Range profile TLV stores the magnitude of 2D FFT values at first doppler bin. Is it true? If so, how shall I convert these integers into the magnitude of 2D FFT values?

Thanks!

Hello,

The range profile is the 1D FFT of the zero doppler (first bin). To understand how to parse the sensor output to generate the plot please refer to the visualizer source code.
