IWR6843AOP: People count solution

Hi,

We are evaluating IWR6843 based mmwave radar product for people count application.

Following is my observations

1. if two persons are crossing virtual zero-line at same time then sensor will detect as one person.

2. If people are walking one after the other with less than 1feet distance, then sensor will detect as one person.

Please let me know how to resolve these observations

Regards
