AWR1843BOOST: The problem about velocity of the ghost object caused by parallel interference

li ch

Part Number: AWR1843BOOST

Hi, the papar (Interference Mitigation For AWR/IWR Devices (Rev. A)) shows that the ghost object caused by parallel interference will has a random distance and random velocity. It is easy to understand the why the distance is random. But I am confused why it also has a random velocity. Can you explain it theoretically? Thanks.

Hi,

Thanks for your patience. The random distance comes from the fact that the parallel chirp may not have same scaling within the bandwidth of all the chirps. Similarly, the velocity can be random. By random we mean that the velocity of ghost object may not be deterministic and also it can get random with the devices clock/crystal frequenceis.

Let me know if you have any questions.

Thanks and Regards,

Akshay
