IWR6843ISK-ODS: Interference Mitigation

Tom Fisher

Part Number: IWR6843ISK-ODS
Other Parts Discussed in Thread: IWR6843

Hi,

My application scenario involves that multiple radars are deployed in a house and could interfere each other.

I saw a video introducing the interference mitigation is embedded in AWR14XX and wondering whether it's also natively supported in IWR68xx.

Thanks

Hi,

Can you explain what feature you are exactly looking at? We should have the hardware feature included, but SDK software release may not actually actively use it.

Best,

Zigang

HI,

The channel quality monitor feature is not supported yet for iwr6843. The expected release time will be second half year of 2020.

Regarding your problem of interference, you probably will be program all the sensor the same chirp configuration. In that case, you will have parallel interference than crossing interference. And the best way to avoid interference is through frame synchronization.
