IWR1843BOOST: Will there be interference if I put two radars close to each other

Hi I am just wonder will there be interference if two EVMs are put close to each other? If so is there a placement guide on what orientations will prevent interference?

Thanks!

    Hi, Zhikai:

    You can find some help from the following e2e thread: e2e.ti.com/.../907655

    In terms of placement, let us assume that there are still interference in your system (you did not do master/slave mode), then

    1) When you place the two EVM back to back,  probably will have very little interference,  In other words, as long as the FOV of the two EVM does not overlap, there should be not much interference.   Very weak interference can happen with multipath reflection.

    2) When you place the two EVM face to face, the interference will be strongest when interference happens (although rare). 

    3) all other placement, the interference level will be in between (1) and (2).

    Best,

    Zigang
