AWR1843BOOST: How to avoid the interference between two radars?

Hi, we want to work with two radars (AWR1843) in the MMR lab transmitting simultaneously.

If I transmit chirps in differents frequencies they will be interfer each other? I mean if for example one radar transmits chirps at 77GHz and the other transmits at 80GHz or could not be an issue to transmitt with both radars at same frequency?

Hi,

Sorry for the delay.

Interference can occur if both radars use same bandwidth frequency.

For example, both radars use 77-78GHz. If one radar uses 77-78Ghz and the other radar uses 78-79Ghz there will not be interference.

Please see this training about managing interference inmmWave radar sensors.

We are also working to release an Interference mitigation demo before the end of the month on the TI Resource Explorer. I recommend you check there later.

Thank you

Cesar
