Turkish Bayraktar TB2 drones from Quora:

"The Bayraktar TB2 drones are small, and fly slowly.

The reigning theory as to why they have been so effective at evading Russian SAM batteries and Jet Fighters is that they inadvertently are taking advantage of an unknown weakness in Russian doppler radar design, which might be filtering them out due to their low speed and small size.

Filters like these are necessary in order to not get all kinds of noise that disrupts operations. Otherwise you’d pick up birds, weather, and all sorts of other random noise, so most of these systems have some sort of filter that eliminates small, slow moving targets.

We don’t know for sure, as these kinds of details in radar design are highly classified, but it appears as if the Bayraktar TB2 falls below Russian filters for speed and/or size. It is unclear if this is the case for other nations radar designs. It is also unclear how easy or difficult it would be to change those settings, or if they are built into the hardware."
