Radar NRA24 behavior

Hello,
I am planning to buy a radar, a NRA24 from nanoradar, and use on a drone for crop spraying.My fear is that the radar will detect the different heights in the crops, and the drone will elevate and descend multiple times.This could impact the spraying process.

Is this problem a reality or am I worrying over nothing?

If it is a problem, what could solve? What I have been thinking was to use the raspberry pi the drone has onboard to read the data from radar first and could do some programming to solve this, and then send the data to my flight controller
