IWR6843AOPEVM: Long Range People Detection

Part Number: IWR6843AOPEVM
Other Parts Discussed in Thread: IWR6843AOP, IWR6843

Dear TI experts,

I am working on a project in which 6843AOP is used to detect walking people in 30~40 meters, however the Long_Range_People_Detection project in the radar toolbox supports ISK alike antennas.  Now I have two options about this: one is to test this with 3D_People_Tracking and another is to modify Long_Range_People_Detection. 

Would you experts please give some advices on:

1. which one I should go first with? 

2. how to modify Long_Range_People_Detection to work with 6843AOP?

Best wishes,

Guolong

    Hi Guolong,

    The Long Range People Detection project uses TX beamsteering, which is only available on the IWR6843 ISK design because its transmitters are located in 3 different horizontal locations. The IWR6843AOP device's TX antennas are shaped in an "L" shape, which means that it does not have 3 different horizontal locations for the TX antennas. This is incompatible with TX beamsteering. Therefore, I would recommend using the 3D people tracking code, or switching to an ISK-style antenna configuation.

    Best,

    Nate
