@H0kram no, radars have no problems detecting slow moving targets and working at low altitude (we are far from the horizon where the curvature of Earth hides low flying objects) The issue is more in the processing of data. Slow moving objects are simply ignored, filtered off, to concentrate on what was thought to be the real threat : fast flying objects, like missiles and AT rounds. Adding the processing of slow moving objects mays overload the computer, which will have to discriminate between birds, tree leaves in the wind, other vehicles, etc… it may require another type of computers, that cannot process fast moving targets but only slower ones (the computer has more data to process, but more time to process them as there are slow). It is not the sensor which is an issue, more the way the data will be processed to make sure only the threats are detected and engaged.

@darthalpha1525 it means you need some processing that can tell apart drones aimed at the tank, people, other vehicles, tree leaves that move with the wind… and, why not, friendly drones that take off close by. It is shape recognition. And remember radars have a low resolution compared to human eyes and are « color blind ». It is certainly something that can be done, but it requires some work

I have the same feeling. I can see of two reasons : it is complicated to discriminate FPV drones from birds, or people walking by. But even an imperfect system would do, the crew would use it only when under threat. Or designs are under way and are not ready yet.
