C4001 25m Radar Sensor - Distinguishing Animals/People from Wind-Blown Vegetation?

I'm working on a project using the C4001 radar sensor for motion detection in my garden, and I'm running into a common challenge that I'm hoping someone here has tackled before.

 

The sensor works great for detecting motion, but I'm getting a lot of false positives from trees and plants moving in the wind. I need to distinguish between:

- Actual targets: Animals and people- False positives: Branches, leaves, and other vegetation swaying in wind

 

I'd really appreciate hearing from anyone who's dealt with similar challenges or has insights into the sensor's capabilities for this type of application.

 

Thanks in advance! 🙏
