IWR1642: IWR1642

Part Number: IWR1642
Other Parts Discussed in Thread: DCA1000EVM

Good day,

I'm trying to run the mmWave Demo visualizer and to get the data of Range-Doppler heat map. There are four RX in IWR1642, I wonder if I can get four Range-Doppler heat maps corresponding to the four RX.

    Hi Yang,

    This is a very good question. For this you would need to alter your chirp configuration to only have one Rx Antenna active at any one time. Since chirps are MIMO configured by default you will not be able to have four different plots at one time.

    Is there a reason you want to measure each of the four Rx Antenna?

    Hi Akash,

    Thanks for your answer. If it's unable to get the four heat-maps corresponding to RX at one time, could I use DCA1000EVM or other devices to capture the data of every RX and handle the data to the get the Detection Range/Doppler matrix corresponding to the four RX.

    BTW, I also wonder the process how to use the data of these four RX get Doppler Heat map, is it possible that by using the mean values?

    Regards,
    Yang

    Hi Yang,

    Yes that would be possible although if you'd like to discuss this further I'd recommend starting a new thread on DCA1000EVM.
